The following books below are considered classics. They were the first books published back in the 1980s by Earl R. Phelps to be specific, “How to Draw your Own Supercharacters” was the very first book published by Earl R. Phelps in 1981. Time goes by fast when you’re having fun. At that time there were very few books on drawing superheroes.
Go back and search your 1980s, and 1990s Marvel and DC comic books and look in the small ad section and you will see a one small ad titled DRAW SUPERCHARACTERS with a Supercharacter on it under E. Phelps Co. The books below are revised second and third printings. Get them while they last. There will probably be no reprints once they are sold out.
