I've looked through my copies of Uneeda to try to find some tell, this is what I've found. There may have been more than 5 printings of the .50 cent cover price version (I think I have 6 based on staple distances of the 32 copies I have). They all seem to have the same thin glossy stock covers, except for one print (the 1st?). One printing has a slightly thicker cover stock and the staple distance between the two (space in between, not including the staples) all are the same on that print. It's a hair under 4 6/10 of an inch apart. Besides that I can't find anything on initial examination that shows any consistent difference between printings.
What are your thoughts on Black and White? Have you examined that title for any tell tale points? How do cover stocks, etc differ on that one?
