I think the covers are great looking. I don't think they're suited for a deck of playing cards. Whatever the topic of the covers. They just don't mesh well. This wouldn't be for me even if I knew the basic details of printing and quantities, which I don't. It's not even on the radar for me.
I hope they consider a coffee table book, with cover reprints in them if they have the license to use them or they're originals what have you. That could be fun.
