1991 Topps #6 Record Breaker - Nolan Ryan
Topps chose to honor the fact that Ryan became the oldest pitcher to throw a No-Hitter, rather than to honor that fact that he had pitched a record 6th no-hitter - which was breaking his own record of five no-hitters.
Of course less than a year later Ryan broke both of these records once again when he tossed his 7th No-Hitter at age 44.
The flip side contains the an Oakland CA dateline and notes the record was previously held by Cy Young who pitched one at 41+ on June 30 1908
Cy Young No-Hitter #3
Boxes don't go back to 1908 in Baseball-ref but we were able to find this line score for the game
Interesting that a No-Htter in a Red Sox vs Yankees (Highlanders) game warranted a grand total of 1 line in the article.
According to the B-R Bullpen the future Hall of Famer almost pitched a perfect game. The first batter Harry Niles walked but was subsequently erased on a caught stealing. Cy Young then retired the last 26 batters to complete the No-Hitter .
