This is how the photo looks with all the color cover versions we've located so far added. I'd like to see if at the least all the comic book covers that are the least bit discernible can be located. It's kind of like a game and a bit of detective work putting this all together.
Robbie, in the photo above, I still have yet to add the last couple of western pulp covers you found. I will do so and post the results after the next batch we find. :-)
The same area that has "Grins", "Hello Buddies," and "Halt!", also has a magazine titled "Keep 'Em Laughing," but so far I can't locate the cover for that issue online.
