A great example of the Nonsuch duratran poster. It's 36" x 36" - and is made of a vinyl-like plastic. The poster was produced to be backlit... place a light source behind it and the colors emerge. For that reason it's tough to get a good shot of it - this one is a wee bit trippy, as it was shot from an angle and later squared-up with Photoshop. Many thanks to Richard Greenleaf!
