From the end of the 1970s to the beginning of the 1980s, over a period of six short years, Eric Ladd painted several SF&F covers. Here is the only (!) information on him on the web that I could find: http://www.isfdb.org/cgi-bin/ea.cgi?27207
His two best paintings are the covers to the first editions of Elizabeth A. Lynn's The Dancers of Arun and The Northern Girl. The German edition of Jessica Amanda Salmonson's Amazons! features an uncensored version (breasts uncovered) of the latter painting and is one of the most memorable fantasy paintings of my life, probably because I fist encountered it in my teens :-)
Does anyone know what happened to him after 1983? Is he still alive? Did he stop painting?
