When I was a kid, I clearly remember a set of detailed coloring books that were famous paintings of the revolutionary war. Several times over the years I have wondered about where I could get those. I think I may have to search again.
Did you ever encounter the series that had panes of colored stamps illustrating the various themes offered. Antique cars, airplanes, historical events etc.
Each page had text and a line drawing, but not the same as the colored stamp. You had to read the text to locate the proper stamp to paste and color in the line drawing.
Loved those soft cover books.
