The Flagstons first appeared in Walker's Beetle Bailey. They spun off into their own strip, written by Walker and drawn by Browne. Lois Flagston (née Bailey) is Beetle Bailey's sister, and the two strips make occasional crossovers. One of these occurred on the strip's 40th anniversary in 1994, when Beetle visited his sister Lois and her family. Chip resembles his Uncle Beetle in attitude and appearance, especially the eyes.
