He also assisted his brother Dan on the Tarzan comic strip for United Feature Syndicate and the Flash Gordon comic strip from King Features Syndicate.

He was hired by Capp Studio to draw Martin Luther King and the Montgomery Story, a comics pamphlet published in 1957.

[4] The Montgomery Story, written by Alfred Hassler and Benton Resnik and distributed by the Fellowship of Reconciliation, "taught young people not just about the event itself but also about nonviolence as a tool for social change."

Many decades later, the comic inspired the March trilogy by Georgia Congressman John Lewis.

[2] Barry frequently used pencil artists on the strip, working primarily as an inker, though he often drew entire stories when time permitted.
