Leonard Starr had a great career, beginning in comic books, going into comic strips (“Mary Perkins On Stage;” after that strip's run he did a revival of “Annie”), wrote the Dargaud Editeur graphic novel series Kelly Green (drawn by Stan Drake), did advertising work, and even worked in animation (“Thundercats”). He retired in 2000 and to the best of my knowledge is still alive at age 86.
In the forties and fifties Starr did some memorable work for the American Comics Group, including the reincarnation-themed “Back to Yesterday” for Adventures Into the Unknown #4 (1949).
As a true illustrator, Starr moved between styles and techniques. For this story he used a Milton Caniff-style of inking, popular at the time, and still popular with me.
