|Initial work on Landscape of a Nation required researching every day of the past 120 years and studying more than 11,000 periodicals, books, interviews, and song lyrics to understand the important themes, events, and individuals of each era. The team reviewed and considered an estimated 4,000 images for inclusion in the mural.
The original mural is painted in acrylic paints on canvas and it covers three 18-foot panels, each 6 feet tall, weighing 300 lbs. Most images required 3 to 4 hours to paint, while others demanded more than 15 hours of detail and attention. Every few years, the mural will be updated and kept current.
