I absolutely have the book MakeMineMarvel shares here, and the Superman and Shazam!  one.  Didnt the Batman one have a cut-out mask on the back?

I recently (last 5 years?) saw these coloring books collected in a shrunk down omnibus like coloring book with a white cover and perhaps Joe Staton cover at a chain of (Formely 5 & 10-like stores) called Dollar General.
