This is an antique "Trent Tile Co." in 6" x 6" square. The Trent Tile Company of Trenton, New Jersey, produced art tiles featuring plants, animals, figures, and other patterns, which were in high demand during the Arts and Crafts Movement of the late-19th and early-20th centuries. Originally founded as Harris Manufacturing in 1882, the companys name changed to Trent Tile in 1883. Isaac Brome, the companys first chief designer, produced hundreds of designs for Trent Tile, and he patented several designs for machines that made tile manufacturing more efficient, cleaner, and more cost effective. The Trent Tile Company was a prolific manufacturer of art tile for decades until financial difficulties forced the company to close in 1939.
