That would be awesome, wouldn’t it? 
My favorite, which I find them hard to find, are optical illusion pictures. Where you look at it one way and see one thing then another and see something else.
Ladies, when i said : don’t hang nudes, i was not referring to cubist art. I was referring to posters of playmates, and sexy picture posters of any woman clearly hung on the wall because it is a sexy poster.
Like this one, a swimsuit illustrated poster of Kate Upton. That one is from the top ten of allposters.com bestsellers list. Home | Art.com
Hanging such a poster in your room gives the impression you’re a male teenager.
Yup. Some art might be an investment, but you can’t buy it based on that (well, not unless you’re buying a Picasso or something like that). Buy what you like and what you can afford - for example, this photo over my bed is a now-famous Stuart Klipper, purchased at a gallery in New York City before this era of his work became well-known. There’s a smaller version in the collection of The Art Institute of Chicago. I probably should get it appraised to get an idea what it would be worth today. The smaller picture to the left is one of my own shots, taken in a normally closed-to-outsiders-no-photography under-river utility tunnel. The only other wall art in the bedroom is a DSOTM platinum record, signed to me by two of the band members. There’s a variety of functional art in the room, like this retro Nixie Tube Clock.
On the crazy side, I knew someone who lived a few blocks from here (since passed away and house torn down) who had a real Old Master painting (painter and subject unnamed to protect the people concerned) hanging in his basement stairwell.
Adults hang whatever the hell they want on their walls, because they are grown. 
Hang up some nude posters of porn stars. That’ll show your friends how mature you are.
What do I prefer to hang on my wall? How do I express my maturity and seriousness?
The severed heads of my enemies.
And if anyone comes over and expresses any type of serious disapproval, perhaps stating how they don’t think this conveys the correct maturity, well… that’s just more heads for the wall. 
Of course, I kid. I’m just kidding. Severed heads drip blood down the wall, and even after they’re bled out, the brains and other headish bits decomposing…
But… I’ve said too much…
Seconding that just about anything will go over, as long as it’s framed, except cheesecakey pictures of women.
Try a good coat of yacht varnish, seals those suckers right up and stops the decomposition completely. Plus, you can buff 'em up to a nice shine too.
At least… that’s what I heard. From a… friend. Yes, a friend told me.
So beefcakey pictures of men are okay? 
I have a framed original 1-sheet from A Room with a View in my living room. It’s a beautiful poster, and it’s collectible, because it’s actually an original from the first run of the film. I got it because I was a projectionist in college for an art film series. I have a couple of other framed original 1-sheets that are from movies not as famous as A Room with a View, and not worth as much, but I think they are attractive.
See, it kind of depends on the movie. If I had a poster, even an original 1-sheet, of the Transformers movie, maybe not so cool. I know a film professor who has a framed poster from Metreopolis in his living room. I have no idea its vintage-- whether it’s connected with the original release, or original US release, or what, but it’s very cool.
I also have a poster I have had since I was ten that says (only in French) “Welcome to the festival of arts in the USSR,” and has a photo of a Bolshoi production of Swan Lake. It’s an official Intourist poster, which was the Soviet tourist promotions organization. We used to get our tickets for the Bolshoi from them when we lived in Moscow. The poster is beautiful, and reminds me of one of my favorite things about my time there.
I have other non-poster things, like family photos. I have a photo of my father, when he was 16, performing on stage as a magician’s assistant. I have my great-grandparents wedding picture. I have a pillow my great-aunt in Slovakia embroidered, that my mothered used for years, but it was getting threadbare, so she had the embroidered section framed. I have the tallis I made for my wedding, that my son was wrapped in for his bris. I have a letter Lillian Gish wrote to me when I was 17. I have a small, 3x3 snapshot matted in a 7x8 frame, of my father reading the comics section to me when I was about 7 months old. I have a page from a first folio, from Measure for Measure. My father acquired it somewhere, and I inherited it. I also have a painting that was my father’s, which is an anti-Stalin painting that somehow made it out of Soviet Russia, and my father had since the 60s.
So, movie posters are just fine. Framing them is a good idea, though. They do look a lot better, and they keep better too. It’s my opinion that having a variety of things is nice, but the poster who said that adults don’t comment on other people’s choice of decor was spot-on. Put up what pleases you.
When I was in my early twenties I had a professionally mounted and framed poster of Pink Floyd’s Wish You Were Here on my wall.
I really liked it, but when I got married I figured it wasn’t exactly the kind of thing my wife would like on our walls. I gave it to a friend from work. I miss that poster, and I hope he has enjoyed it and taken care of it over the past 24 years. I can’t get another one—my wife’s opinion has not changed.
That’s why you put them on the spikes of your iron-grille fence, silly! Much easier to clean, much more effective at keeping undesirables away.
No, thanks, it’s getting kind of late.
…
:smack: Damn it! “Etchings” is “sex”!
Couldn’t tell you, I don’t think I am a mature adult. On my walls:
A Larry Elmore painting.
A Magic Eye poster.
A magic winter/summer picture that changes seasons depending on the angle you view it.
The Kramer.
A guitar-shaped clock.
A Backwards Clock.
I’ve got a framed print of M.C. Escher’s Ascending & Descending in the den.
He is a loathsome, offensive brute, and yet I can’t look away.
I didn’t know this was available!
Oh, man, I am green with envy! I would love to own a Cygnus. That, and a Revell “trash can” space station.
