Possible Bald art per Nick Caputo, June 2023. Previous indexer credited Ogden Whitney.
Flash is the Hooded Horseman's dog.
GCD Mail page suggests this to be art by McCarty, and the faces and horses compare well with signed or credited work on Kid Colt Outlaw #50 (Marvel) and in Black Magic #16 (Prize). He is not found in Jerry Bails' Who's Who. The inker is not certain.
