These feel like cardstock or thin cardboard but on the front there is a plastic or treatment that let's it be wiped off, it gives almost a holographic appearance I was able to catch in a few photos. One of them has a yellowed back, most have a little dirty spots on the back, nothing major, I did not attempt to clean off. They are in original box, which has shelf wear and a tear on one corner.they are 14" long and 20" wide. These would be beautiful to frame. Please look closely at.all photos as they are part.of the description.
