I never realized, until he spilled the beans in monograph, that there were two sets of cards on the back cover. And, now I see that there is a blurry and a sharp version of the cover. Are they all from one printing? The paperstock is different on my blurry copy and my sharp copy. The blurry printing I have is softer inside and the see-through back page activity works better. The sharp printing I own has a very shiny overly rich quality.
