When I was a kid, I bought a lot of comic books published by Dell. Where I lived, they seemed to have the best distribution of all the comics publishers, because they were all over the place. Disney stuff, movie and TV tie-ins (two I remember distinctly are THE COMANCHEROS and 77 SUNSET STRIP), Tarzan, the Lone Ranger . . . Dell had great stuff for an eight- or nine-year-old.
What I didn't know then -- and probably wouldn't have been interested in if I had -- was that Dell also published three issues of a comic book based on the exploits of redheaded Miami shamus Mike Shayne. I found out about these years later but have never tried to get my hands on them. But the other day, my buddy Jim Doherty from the Rara-Avis list posted a link to the covers of the three issues, so I had to take a look. They're pretty good. This is the cover from the second issue, and you can see the other two here. I'm tempted to start searching the Internet for these. Maybe one of these days.
