What is the traycase for the numbered S/L Subterranean Press The Shining made of? Is it leather, or something similar? Or is it cloth or something cloth-like? The reason I ask is because all the pictures of these traycases on ebay always look like they have smudges or fingerprints or dark marks on them. Is it just a trick of the light or the material maybe? See below links to a couple of ebay listings for examples. Both examples have darker areas around the traycase that look 'smudgy,' for lack of a better word.
