Here is a perfectly signed 1987 Perez-Steele Great Moments postcard of legendary Yankees slugger Mickey Mantle. Shown bearing down a pitch from the right side of the plate, Mantle appears ready to launch yet another home run for the Bronx Bombers. The 5 ¾” by 8” postcard, which is numbered 2379/5,000, boasts a beautifully scrawled signature in blue fiber-tip marker from old No. 7 that has been authenticated by JSA.
