Creator of the unsophisticated sitcoms for CBS, most notable the Beverly Hillbillies, Green Acres and Petticoat Junction. DS, one page, 8.5 x 11, June 20, 1963 on Beverly Hillbillies TV show letterhead. Tongue-in-cheek memo to the cast of The Beverly Hillbillies preparing for a grinding schedule of shooting. In part, “The three week period…will be weeks of super intensive effort for all of us. We must film at least five shows during that period…preferably six! This will require us to shoot five 10-hour days each of those three weeks. Therefore, in the interest of harmony, unity, and sanity I urge you most strongly to forego all outside activities during that period. Don’t schedule interviews, trips, orgies or other enervating ritualistic revels…Gird your loins, oh followers of Thespis! This can be your finest three weeks.” In fine condition, with adhesive remnants to reverse. RRAuction COA.
