Johnson (b. 1943) played in the majors from 1969 to 1974 and 1977 for the Mets, Royals, Pirates, Indians and Braves. He had a record of 28-34 with 507 strike outs and a 3.48 ERA. He won the World Series with the Pirates in 1971.
I mailed to Johnson on October 8 and got the cards back on November 3, for a 26-day TAT.
