Possibly could have holes, tape, bends, folds, and rolls from age and years of waiting for the next forever home. not currently in a smoke-free home, but......it comes from the straight '60s/70s, so who knows past life.
I can't find anything on this poster not even Google Lens comes up with anything. lots of hidden messages and words but not sure what it is.
size is about 36x24
