I know there was a tradition of 'Letterzines' in U.S. and U.K. S.F. fandom, but I don't know if the same held true in Comics fandom?
In the U.K. the best known example was probably 'The Owl’s Effort' by Comic and Soul music dealer, Richard Domar.
TOE grew out of Dick's sales list; A6 in size, and using double reduced type, it always covered much more than just comics talk. Dick had a very forthright character, and you could be sure of a passionate and lively argument on a host of topics, if that's what you were looking for.
As the letters sometimes contained very personal information, the zine isn't one I'm looking to archive. It did though, always contain some lovely artwork, which I think people would like to see.
This issue from 1982, sports a lovely cover and strip work by Don Wazejewski (who illustrated Cosmic Cowboys and Battlehawks for Battle in the late 1980s).
