Perhaps the rarest signature in Perez-Steele's groundbreaking first postcard set, Hall of Fame President Paul S. Kerr was a difficult autograph acquisition to begin with, but he also died in 1984, just three years after his card was released. Kerr devoted more than 30 years of his life to the Hall, arriving soon after its grand opening in 1939 and helping shepherd its evolution from a two-room building to a sprawling mecca for tourism and research. He preceded Edward Stack as president from 1961 to 1978, as well as served previously in the capacities of vice president, treasurer and secretary. Another claim to fame is that it was Kerr who disclosed Sam Rice's posthumous letter stating that he did in fact make the controversial catch in the 1925 World Series.

At first glance from arm's length, the Perez-Steele card appears EX or better, with closer scrutiny revealing GD/VG condition due to peripheral creasing. Kerr's signature is a black-ink "7-8" example. The last record of a Kerr signed card hitting the auction block was in 2013 for over $5,000. A near-complete signed set that included Kerr (and lacked only Satchel Paige) sold in 2020 for just shy of $30,000. Kerr remains the elusive missing link for many a completist collector!
