Locus Online reports the death of artist / illustrator Leo Dillon who, along with his wife Diane Dillon, illustrated numerous SF novels including many covers for Ace Books in the 1960s. The duo are particularly well-known for their iconic cover and interior illustrations for Harlan Ellisonâ€™s Dangerous Visions anthology.
They are the only artist team to jointly win a Hugo for Best Professional Artist (1971), and they received a joint World Fantasy Lifetime Achievement Award in 2008.
