Two signatures from legendary switch-hitter Mickey Mantle comprise this lot, with both items having been signed at IBM's Watson Trophy Dinner in Endicott, NY. Mantle was a guest speaker at that 1974 event and his image is illustrated on the cover of the yellow, 5.25x8.25" program, which has a vertical crease in the middle from top to bottom, though it does not affect display quality. It is signed on the cover in black ink, with slight watermark towards the end of "Mickey."Both ball and program are certified by PSA.
