4 Miniature Marvel Comic Books from 1966, possibly part of a promo giveaway in a gumball machine like shell. I do not have the cases for these and am not an expert, but would probably grade them as FAIR. Captain America - blue book, Hulk - green book, Sgt. Nick Fury - yellow book, and Thor - orange book. Some of the pages are loose and/or missing back covers. Please review pics, and ask me any questions you may have before bidding.
