This volume of the acclaimed Sunday newspaper strip starts with Prince Val trying to bust Sir Gawain out of jail, and includes a quest for the Holy Grail.
Hal Foster (1892-1982) created Prince Valiant in 1937. Though remaining involved with the strip until his death in 1982, Foster handed the bulk of the scripting and art chores over to his longtime assistant, John Cullen Murphy, in 1971.
