Early blue ink signature, “Charles M. Schulz,” on a 6.5 x 3.5 postal cover (postmarked 8/26/52). In fine condition, with faint perimeter toning and an affixed magazine photo above the signature. When this cover was signed, Schulz was a budding 29 year old cartoonist and Peanuts, which first appeared in October 1950, was in its infancy. RRAuction COA.
