I only have posters with one bent corners remaining. Pictures of the stack in the photos. I think if you are going to frame these it would not be too noticeable. 18"x24" poster screen printed on heavy paper with black flocking (velvet). The fluorescent colors glow under a black light.
Posters will be shipped in a large tube, as Priority Mail which averages 2 days delivery in US . USPS doesn't offer tubes to be mailed as First Class any more , so shipping is a bit more for posters.
