Originally credited to Clem Weisbecker, but this is Harry Anderson, who can be spotted by his unique faces with eyes that have a straight lower lid and high arched upper lid, and small lines outside the corners and thin, long eyebrows. On the two last pages can be seen some clenched fists with short lines beween the finger not going all the way down, another peculiar sign of Anderson. He is credited on this feature by Jerry Bails' Who's Who, and had many Nyoka stories, and also the Red Gaucho to compare with.
