I was reminded by Infovore’s post about Alice Cooper in a thread on seeing bands that back in the Paleolithic Era, my friend Vic went to an in-store event at Harmony House outside Detroit and got Mr Cooper to sign his copy of the AA book members call Big Blue. Their shared bond in fighting alcohol addiction was important to Vic, more than an album or photo or other, more run-of-the-mill, ephemera.
What unique item have you or someone you know given a celebrity to autograph?
I hope this isn’t considered a hijack. It’s meant to be an interesting related story. Last night I was watching Jimmy Fallon and Tina Fey play a game called Best Friends Box (Challenge?) where they read a question and then both of them write the answer on a note pad. There was a question something like “If Tina Fey were a cereal, what cereal would she be?” Tina Fey made up an answer: “CORN BLASTERS” which for some reason I thought was funny as hell. My next thought was how fun it would be to have a sheet of paper that had CORN BLASTERS on it, autographed by Tina Fey? That would definitely qualify as a unique autographed item! 
I carry a couple of crisp dollar bills in my wallet for this reason. I once ran into Dave Stewart (baseball pitcher, 1989 World Series MVP) on a plane at the St. Louis airport, and he graciously signed one for me.
I also have a book of the NFL’s 75th anniversary and have collected several autographs in it over the years: Jerry Rice, Sammy Baugh, and Jerry Kramer so far.
When I first moved in to my own house, I spent a ton of time watching “alternative comedy”-era British comedies, like The Young Ones and all related series and casts.
A year or so into it I realized I didn’t have any art in my home and I should have some art, something that inspires me, and I was like “what do I really like?”
So I purchased an old cricket bat off eBay, figured out how to get in touch with Adrian Edmondson’s management [he is one of the aforementioned alt-comedy stars], shipped the bat off to their offices in England, Ade signed it and I paid to have it shipped back.
My favorite art 
ETA: Also, I recently met Carroll Spinney [Big Bird] at a comic con, and had him sign the cover of a VHS copy of Christmas Eve on Sesame Street.
I have a Barney doll signed by James Marsters (Spike, on Buffy the Vampire Slayer).
We were standing in line with our 1yo daughter and they started playing a selection from his band’s music. Sophia (the kid) started bouncing up and down, being really cute, and Marsters volunteered to sign her Barney, given she was “such a fan of my work.”
Not me but…
We recently had the Star Wars Celebration here in Orlando with an appearance from Hayden Christensen. Someone waited in line to have him sign…
…a jar of sand.
Brilliant and hilarious. Hayden was OK with it and thought it was pretty funny too.
A copy of my book, signed by more than a dozen big names in sf and a few very rare ones.
A plastic cocktail glass, inscribed “From one loser to another, Allen Steele.”
I have one of only two of these in existence.
In 2014 a friend and I went to Philadelphia to the NHL draft. It was a trip contest sponsored by the Edmonton Oilers, so we were there as their guests. We watched the picks from the Oilers box (while chatting with Semenko and Messier).
Earlier she and I picked out an official draft shirt and had them with us in the box. After Draisaitl was picked, he came up to the box to sign contracts and he also signed our draft shirts.
So, while having a shirt signed isn’t really unique, we have the only 2 of these that exist.
Klay Thompson of the Golden State Warriors was asked to sign someones toaster recently, I believe the warriors are undefeated since that day.
The Warriors eliminated the Spurs last night to become the first-ever NBA team to go undefeated, 12-0, to get to the NBA finals. They will play the winner of the Cavs-Celtics series.
I looked it up and they are 27-0 since Klay signed the toaster, but only on games he played. They lost one regular season game to the Jazz when Klay was out.
Ok, that is fantastic!
Barry Bonds, while playing for the SF Giants, was known for not signing autographs. It was very difficult to get his autograph. Bonds, who is the best player I have ever seen play (I was too young to see Willie Mays), as many people know, can be a real jerk. A real dick. This is a true Bonds-the-dickhead story, a Bonds autograph story. Apologies for the hijack, it is somewhat related.
Before playing for the Giants, Bonds played for the Pirates, his first MLB team. Back then, he and Bobby Bonilla formed the core of some very good Pittsburgh teams. A good friend of mine brought his kid to a Pirates @ Cardinals game. They waited to get some autographs. Bonds, earlier in his career, was there and my friend asks if he’ll sign his son’s glove. His son had a nice collection of autographs on his glove.
Bonds takes the glove, looks carefully at it, turning it over, looking for a nice and prominent place to sign, and then signs it with a magic marker. Bonds hands the glove back to my friend and his son.
They looked at Bonds’ autograph. Bonds had signed largely and prominently right over Bobby Bonilla’s autograph, essentially ruining both autographs.
A total dick move by Barry Bonds. Yes he’s the best player I’ve ever seen play. But he is a dick.
Which is why, if I ever meet the man, my first words to him will reference Francisco Cabrera.
Many years ago, there was a biography of Monica Lewinsky published. She did a book signing at a local bookstore in Los Angeles - I attended and got a couple copies signed. (If I recall correctly, she was not normally doing signings and this was a one-off occasion.)
A few years later Hillary Clinton published her book, and was doing a book signing. I so wanted to take the Monica Lewinsky book and try to get Hillary to sign it also, historical significance and all. But, I didn’t have the guts to try. Hillary’s book signing rules stated she would only be signing her book! And I figured there would be a team of security available to handle any disruptive types. So, a dream I didn’t act on.
Kid
had something of value and Bonds ruined it. I wish that the kid’s father had sued for damages.
You mean since the Lakers did it.
I got Yogi Berra to autograph a can of Yoo-hoo.
Just a few years ago I learned that’s common practice among authors at their book signings; their books only, and sometimes ONLY books. Which makes sense, but it’s nothing I would have thought of.
There’s a song called Sign My Snarling Doggie by The Bobs; it’s about someone who goes to an autograph show and asks Mickey Mantle to sign his dog. Well, I was at a Bobs concert, and when they started this song someone in the audience brought a stuffed toy dog and a pen to the stage and they all signed it.
Sometimes I think there’s a song for every conceivable topic in the world.
