While I wasn’t a big fan of Thor, I couldn’t resist this treasury comic when it came out – an epic battle (actually battles) between Thor and Hercules, plus the pantheon of both Asgardian and Olympian gods. This reprints Journey into Mystery #125 and Thor #126-130. The treasury comic format didn’t work well with some artists, but actually highlights Jack Kirby’s style perfectly. Giant pages for battling giants!
