Last appearance.
Originally credited "Bill Ward ?"
The art is similar to Kirkpatrick's work on several Sally O'Neil in National Comics and Hack O'Hara in Crack Comics. Many faces in sideview popping in from the sides, bony noses in frontview, very wide trouser legs, and also rather still standing figures. Inking uncertain, as she had much pencil work for Quality Comics.
All Gustavson credits verified and courtesy of Terry Gustafson, son of Paul Gustavson.
Final appearance of feature. Other publishers will have features named Roscoe, but they are unrelated.
Last appearance in Feature Comics. Perky will move to Doll Man (Quality Comics, 1941 Series) starting with issue #22.
