Toned and clear coated official baseball having been hand decorated by folk artist George Sosnak picturing hand painted scenes from the April 9, 1962 homer opener for the Washington Senators against the Detroit Tigers. President John F. Kennedy was in attendance to continue the long running tradition of throwing out the ceremonial first pitch as memorialized by Sosnak on a side panel. The ball has been autographed on behalf of President Kennedy by his secretary, as commonly seen, in blue ink across the sweet spot. The signature has been partially enhanced for artistic eye appeal by Sosnak in black ink as typically seen of his works from the period. Fine surface patination with rich color and intricate detail work. Remarkably, the ball is accompanied by a typewritten letter dated October 1, 1962 from Evelyn Lincoln to George Sosnak. Lincoln was the personal secretary to the President and notes within the letter, in part, "He was very glad to autograph your baseball and it is returned herewith." Outstanding and important Sosnak example with direct provenance: EX
