I also got two different 1972 Topps signed, along with a 1973 and a 1976. His signature is really nice, and looks good on all of these cards.
Kranepool (b. 1944) played in the majors from 1962 to 1979 for the Mets. He had 1,418 hits, 118 home runs and a .261 batting average. He was an All Star in 1965 and won the World Series with the Mets in 1969. He appeared on the 1985 Hall of Fame ballot, but did not receive any votes.
I mailed to Kranepool on October 3 and got the cards back on October 13, for a 10-day TAT. I paid a fee of $20.00 ($5/card).
