Hal Foster drew it for more than forty years, with his signature last appearing on the page in 1980. It has continued to be drawn by Foster's long-time assistant John Cullen Murphy and it is now written by Cullen Murphy, the son of John Cullen Murphy. In addition to Hal Foster's Prince Valiant pages, the Cartoon Research Library has a fine collection of Murphy's original Prince Valiant comic strips that he donated in 1992. The entrance to Cartoon Research Library is at the north end of the Wexner complex grid. Its regular hours are 9 a.m. to 5 p.m. weekdays.
Hours vary between terms.
