You may not be surprised to learn that most people in the comic business grew up reading comic books. However, you might be interested in knowing what they were reading. Here’s a look at “Famous Fanmail”!
Gary Groth founded Fantagraphics in 1976, a comics publisher well-known for their alternative publications and their comic news magazine, the Comics Journal (featuring significant contributions by Groth, himself). Years before his successful run as a comics publisher, he got a letter printed in Thor #162 (cover date – March 1969).
