Called The Richest Square Mile on Earth, Central City, Colorado, produced millions of dollars from its ores of gold, silver, copper, lead, and zinc around the turn of the 20th century. Underground mines such as appears in this watercolor by Pat Patterson unearthed these riches from deep mines that reached thousands of feet below the surface. Colorado artist Pat Patterson studied at the Chicago Academy of Fine Arts under Ruth Van Sickle Ford and worked as an artist with the US Navy during WWII. He then settled in Denver, Colorado, producing pen & ink and watercolor illustration for the fashion industry, books, and limited-edition prints. Professionally mounted and framed in pecan-toned wood and plexiglas, finished size is 27-3/8 x 23-5/8 inches with matte opening of 17-7/8 x 13-7/8 inches. Central City Colorado
