These 18 baseballs primarily center on the 1977 and 1978 Yankees, and there is an abundance of clubhouse signatures. The majority have clubhouse Billy Martin and Thurman Munsons (two real Munsons, one from 1977 and the other from 1978, his last two full seasons). The lot Includes a 1960s Old Timers Day ball with Joe DiMaggio, Red Rolfe and Frank Baker. There is an unsigned Lee McPhail ball and one Japanese-signed player.
