Roy Crane practically created the adventure comic strip with his fantastic Wash Tubbs and Captain Easy and Buz Sawyer comic strips. Roy Crane combined breakneck action and nail-biting suspense with a bigfoot cartoony style that produced a timeless classic strip that would influence the biggest names in 20th century cartoon art, including Milton Caniff, Wally Wood, Harvey Kurtzman and Charles Schulz.
