During World War II the government asked newspaper syndicates to reduce their strip size in order to save more paper for the war effort. Since King Features had the whole Sunday page with their Prince Valiant feature, they quickly asked Foster to create a new strip so as to not lose any space to one of their competitors. The artist came up with a three panel strip, which usually ran at the bottom of the Valiant page, about two young English squires named Arn and Guy at the time of the First Crusade.
Artist and Creator: Hal Foster
