As you may have guessed by now, I love anything to do with photobooths, even the signage from them.
The fifty cents sign is aluminium. I guess that was cheaper to change as the prices went up. The other two are much heavier and possibly made of stainless steel.
They all come from the USA, via France. I bought them from the author of a famous book about photobooth photos, but more about that in another post.
