1) Fathers Day
2) I believe that made Bunning the 1st pitcher to toss no-hitters in each league in the 20th century. Cy Young had done that feat but his NL no-hitter was in the 19th century.
3) Rick Wise would win his 1st major league game in the 2nd game of the double header. Rick Wise's RC also includes this great typo for the other player pictured:
This 19 year-old right hander is only 18 years old.
4) Bunning also joined a very exclusive group to have pitched both a perfect game and another no-hitter. Cy Young and Addie Joss had already done that; Sandy Koufax (the next year); Mark Buehrle and Randy Johnson would join that group in the next 45 years.
Anything I missed
