"Fiorello Henry La Guardia (December 11, 1882 – September 20, 1947) was an American politician. He is best known for being the 99th Mayor of New York City for three terms from 1934 to 1945 as a Republican. Previously he had been elected to Congress in 1916 and 1918, and again from 1922 through 1930. Irascible, energetic, and charismatic, he craved publicity and is acclaimed as one of the greatest mayors in American history."

John Francis Hylan www.wikidata.org/wiki/Q6233903

The curved detail on the top edge of the wall places Mayor Hylan at the Polo Grounds, as he poses prior to throwing out a ceremonial first pitch. (See comment by Jon (LOC P&P) below). The date inscribed (in reverse) on the bottom of image reads "10/6/24," which would make the occasion Game 3 of the 1924 World Series, between the New York Giants and Washington Senators. The first game of the series to be played at the Polo Grounds. The Giants would defeat the Senators that day, by a score of 6-4, but the Senators would ultimately win the World Series (their first World Series Championship) in seven games.

Thanks TVL1970. The New York Times article published on October, 7th, 1924 says Hylan posed for the photographers with a ball, but didn't actually throw it.
