Fight night at Gleason's Gym.

According to Wikkipedia:

Gleason's is a boxing gym located on the Brooklyn waterfront. Since 1937, when the gym was founded in the Bronx, boxers with their eyes on Olympic glory or a shot at the title have been training at Gleason's. Fighters who trained at the gym include Jake LaMotta, Roberto Durán, Benny "Kid" Paret, Gerry Cooney, and Mike Tyson. Before his first title fight against Sonny Liston, Muhammad Ali, then known as Cassius Clay, also trained at Gleason's.

The gym was founded by Peter Gagliardi, a former welterweight, who changed his name to Bobby Gleason. It moved to Manhattan and then to Brooklyn. Gleason's is now owned by Bruce Silverglade.

There is a sign on the wall at Gleason's, posting an invitation from the poet Virgil: Now whoever has courage, and a strong and collected spirit in his breast, let him come forth, lace up his gloves, and put up his hands.
