These books come from different sources: the first, Heathcliff: Round 3, collects cartoons from the newspaper panel. In previous reviews of Heathcliff collections, I’ve mentioned that this meant that a book hit a lot of common tropes that are better separated over the weeks of a cartoon’s run in the papers.
Heathcliff: Treasure Chest, on the other hand, collects Heathcliff stories from the Marvel comic books, so each runs a couple of pages as you would expect in a comic book. There are little adventures where Heathcliff is on television or wins the lottery, and they do expand upon the humor in the cartoons, but even so, two of the cartoons collected in the book repeat a plot (Iggy and Heathcliff get locked somewhere with burglars).
Both are amusing in their way, and worth flipping through if you can pick them up for a quarter. Also, children love them.
