Here’s a “missing” 1977 card for former infielder Rob Sperring, who appeared in 43 games for the Chicago Cubs in 1976, generally playing third base and shortstop:
In that time Sperring batted .258 with 24 hits over 93 at-bats with three doubles and seven runs batted in.
He would end up playing the last of his four-years in the Major Leagues
with the Houston Astros in ’77, getting one last card in the 1978 Topps
set to close out his career, batting .211 over 208 games with exactly
100 hits in 473 at-bats.
