Here's a source: Yes that's correct, it was called "premium" because I used the highest available print quality. If I recall the difference was quite small, but printing cost about double.
Interestingly I still have a handful of "scraps" of the signatures and holograms leftover from the Autographs Edition, I don't know how many but I'd say about 20 substantial sets, which could be used in some special way down the road.
any chance of selling a set to go inside my book? dont know if that would be crazy priced or not
Not at the moment as I don't have them nearby, but I can take inventory this spring/summer and see how things look. If I have an even number like 10/15/20 I'd think it best to preserve for a potential future edition or project.
