George R. R. Martin and the Avengers

Claudio Sanchez, lead singer for one of my favorite bands Coheed & Cambria, is also a hardcore comic book reader and fan (FYI: he has his own line of comics based on the storylines that pervade the Coheed & Cambria albums). Yesterday, he Tweeted the picture below. Apparently George R. R. Martin, the writer of the A Song of Ice and Fire series (most people might recognize the first book, The Game of Thrones, since it's now a popular HBO series), wrote a letter to the Marvel Bullpen back in the 1960's and had it published in Avengers issue #12 which, according to my basic research, hit the shelves in January, 1965.
