Kelly Freas was a giant of the field. I had the pleasure of meeting him at Loscon one year, and he was utterly charming.
A lot of his color work, especially later on, is a bit garish for my personal tastes, but he’s another one who had fantastic pen and ink interior illustrations and I love his author and editor portraits. And, boy did he know his way around rocket ships and shapely women.
