This vibrant vintage linen postcard beautifully depicts the downstream face of the Hoover (Boulder) Dam, showcasing the power house and water cascading higher than Niagara Falls from the canyon wall outlet works. The image captures the iconic dam nestled between rugged canyon cliffs with water pouring through the diversion tunnel outlet in the foreground. Printed by Desert Souvenir Supply of Boulder City, Nevada, this postcard is a classic example of mid-20th century American souvenir postcards, noted for their textured linen finish which enhances color saturation and detail.
