Just got a few more issues from my personal pet project of the past few years: Adventures of Peter Wheat. It's still not a very high profile title, but it's extremely hard to find and very well done.
In reverse order:
#38. One of the earliest Al Hubbard issues. Hubbard is not exactly what I would call a big name, but he had a couple of long and underrated runs on series; Mary Jane and Sniffles in particular is a favorite of mine. His Peter Wheat work pales in comparison to Walt Kelly's run, but is extremely good on its own terms.
#30. But, as I said, Hubbard's work is nothing compared to Walt Kelly's run on the title. Since the covers double as the first page of the story, they rarely pop like some of the interior shots do once the story gets rolling. For my money, Peter Wheat is Kelly's finest work in comic BOOKS as opposed to strips.
#25. This is actually part 2 of 4; and since I found #26 a couple years ago (and then was able to figure out which issues the storyline actually ran) completing it has been my personal most wanted book. It's not flawless, but taken as a whole it's an absolutely amazing 64 page fantasy-adventure by Walt Kelly that I think is only not regarded as one of the greatest pre-code stories of all time because almost nobody has ever seen the whole dang thing! This was the last issue I needed to put together the story, and for me at least it's as exciting as any find I've ever made.
