The August 30 1924 edition of the Toronto Daily Star is turning out to be a good source of material! Here’s another photo, of a baseball player who sold himself for $11,000:
A search for Frank Walker in the Baseball Reference website revealed that while he might have sold himself to the New York Yankees, he actually wound up playing for the New York Giants in 1925. He batted only .222 in 39 games, and this was his last year in the major leagues.
He returned to the minor leagues in 1926, spending the next four years as player-manager with Greenville of the South Atlantic League. He continued to play minor league baseball until 1931, and passed away in 1974.
$11,000 was a tidy sum of money in 1924, by the way: it is equivalent to over $166,000 today. Mr. Walker was a good businessman indeed.
