So by definition a unfolded poster must have folds. otherwise you would not be able to unfold it.
And here's a few more rolled posters... Well technically flat, as I store them flat...
Technically this is an unfolded poster as I believe I see a fold. This poster must be removed and put in an unfolded poster thread
Ohhh bum-titty bum-titty bum
Creases are try hard folds.
It didn't try very hard, it barely makes it to the bottom of the R..
Infolded one sheets for Vynález zkázy (the fabulous world of Jules Verne, 1958) and Bessmertnyy garnizon (Immortal garrison, 1956)
Ok, so it is a partially unfolded poster
