I was surprised to discover these vintage 1977 comics fro New Dimensions in Education. These comics were likely never for sell, but were part of the Letter People learning program which was so popular in pre-schools and kindergartens once upon a time, and may well still be for all I know.
What prodded my interest, aside from the charming spin on super heroics the covers display is that by all appearances they were done by Wayne Howard, the former Wally Wood worker and Charlton mainstay who was responsible for one of my all-time favorite comic books, Midnight Tales. The last two issues of this run (I could not find a scan of issue number one alas) are signed by Howard and the other covers appear to be his work too. I wonder if these books were produced in the Charlton offices as were other educational materials from the same era, most notably the Popeye career series. I'd love to find these comic gems somewhere, they are just that offbeat and interesting, truly charming.
Here's a glance at The Letter People in all their color-saturated psychedelic glory. Kookooachu!
