I have to admit to currently being a really big Usagi Yojimbo fan, the comic series written and drawn by Stan Sakai. But, I would never have discovered Usagi if I had not first been a Groo fan. Actually, I doubt that I would even be a comic fan now if I had never discovered those first few Groo comics I read.
Everything you have listed above is in my collection, as well as most of Sergio Aragones’ other comic work.
