In 2012, The Encore Park Project Committee commissioned Brad Oldham and Christy Coltrin to create original artwork for the amphitheater walls that denote the former perimeter of the Columbia Film Exchange Building at Young and Park. They were inspired by the history of Dallas up to the mid-1930s when the city made its remarkable step onto the world stage and when important recordings were made at 508 Park. Drawing upon a 1930s mural by Jerry Bywaters and Alexandre Hogue for the Old City Hall (painted over twenty years later), they created a lost-wax bronze sculpture wall that features iconic and lesser-known visual stories unique to Dallas. These stories are told across ten 6-foot by 4-foot bas relief panels along Park Avenue and Young Street that create the site-specific installation called The Birth of a City.
