Jay Hanna "Dizzy" Dean, the brash Cardinals fireballer, made his major league debut on the final day of the Cardinals' 1930 season, surrendering just three hits as the Cardinals defeated the Pirates 3-1. He averaged 24 wins over his first five full campaigns. A winner of four consecutive National League strikeout crowns, Dean was 30-7 in 1934, (and the last National League pitcher to record 30 wins) when he and his brother Paul led the Cardinals "Gashouse Gang" to the World Championship. A broken toe suffered in the 1937 All-Star Game led to an arm injury that eventually shortened his playing days. He later embarked on a successful broadcasting career.

This agreement is the transfer agreement, between Dean's minor league team, the Houston Buffaloes, and the St. Louis Cardinals. It is signed by the president of the Houston team, Fred "Pat" Ankenman, and Cardinals owner, Sam Breadon. In short, this piece of paper sent the great Dizzy Dean to the Major Leagues where he became a legend.
