Wow! When John was the special gust star at Philadelphia's WFIL "Helping Hand Marathon," he personally autographed this blue denim cap. The show was held May 16-18, 1975. John also added his signature face doodle beside his name. The cap includes the button for the event for the employee who worked the show and sold our consignor this treasure. NRMT. Leland's has also found and included a (Xerox) copy of the handbill for the event.
