In what is now Monument Square, Tom "Piggy" Huston, a Portland butcher, is shown on a horse-drawn sled loaded with two pigs.

On the right is Squire Jonathan Morgan.

In the background is old City Hall, where the Soldiers' and Sailors' Monument now stands.

Nicholas Winfield Scott Leighton (1849-1898) was a painter who worked out of Boston, MA. He was primarily an animal painter, with a heavy focus on horses. In 1874 he opened his own studio in Boston, which he ran until he was institutionalized at MacLean Insane Asylum, where he later died.
