Oh, carrps, I wish I could get that sign!!!
What about the Plymouth Valiant with the pushbutton transmission. I used to drive one of those.
Try to google for it. I’ve had it maybe 6 or 7 years it might still be around.
Good news and bad news from the Lost and Found Department.
This isn’t exactly a sign - it’s a “message” on the side of a F1 car - but it’s funny (and clever) so I’m posting it anyway.
Back in the day, Jordan racing were sponsored by Benson & Hedges, a tobacco company. Here’s a picture of the EJ 11 car - you’ll have to click on the image/link to jpg to see properly that it displays the name Benson & Hedges prominently on the rear wing and the side of the car. (Aside - I was going to spoiler these pictures, but it turns out I don’t need to - cool!)
With pressure from major markets to stamp out tobacco advertising, F1 introduced a rule preventing cars carrying the name/logo of tobacco companies. The guys at Jordan found a way to sidestep this - at least until the rule was modified:
Other “messages” the cars carried at around that time were Buzzin’ Hornets and Bitten Heroes

I saw a truck something like this one on the road once, with a smallish inconspicuous bumper sticker on the back that said simply “Ichabod”.
Some years ago – back during the 1972 election season to be precise – I saw a car with two Nixon bumper stickers, carefully dissected and arranged to say " NIX ON NIXON ".
Reminds me of the “Escape to Wisconsin” bumper stickers I saw when I was living there in the '80s. Sometimes the “to” was cut out, with which I heartily agreed.
If it was on the wing of the car, wasn’t it already spoilered?
Perhaps they had another truck named “Frasier.”
Funniest joke from, “Frasier”:
Daphne had put on a lot of weight (Jane Leeves was preggers at the time) and was down on the floor for some reason and couldn’t get up. Frasier, Niles and Martin latch on and get her up. Martin mumbles It took three Cranes to lift her.
I heard of a bumper sticker in Atlanta from an aggrieved sports fan.
“Go Braves!
And take the Hawks with you!”
…
There’s another bumper sticker that I’m particularly fond of:
“wag more, bark less”
I went to the original Archie McPhee (Accoutrements) store and got a cool shirt with this phrase and a boxing monkey (of course in a fez!).
Many years ago I reported on a sign I saw while cycling near where I was working at the time. It was attached to the metal fence in front of what appeared to be a normal suburban house
WARNING
DO NOT ENTER WHILE ALIVE
(Don’t have a picture. Sorry)
I still don’t know what it was supposed to mean. Was this a Zombie Retirement Community? Was this an electrical warning not to enter while the system was “live”, and the guy just took it and stuck it on his home?
I would assume it is a cousin of the “No Trespassing - Survivors Will Be Prosecuted” sign?
I remember a sign on a chain blocking a path that read, “Ain’t Nothing In This Hollow Worth Dying Over”.
Simple and to the point.
Years ago, a restaurant in Minneapolis hired a young Japanese immigrant as a waitress. If a section was temporarily closed off, she’d post a handwritten sign saying “Is closed please.”
Kind of charming when you think about it. 
“Beach Logs Kill!” – actually a pretty serious warning posted in spots around the Olympic Peninsula. The first time I saw the sign I thought it would make a good poster for a B horror movie.
Another sign I saw nearby at Dungeness Spit had the heading “Enjoy The Spit!”
I took a picture this morning:
Love the cactus/succulents. We have similar, but indoors.
I came in here to specifically post my favorite variation on this. The arrow on the left said “Overtaker” and the arrow on the right said “Undertaker.”
