The iconic Gateway Arch commemorates St. Louis' role in the westward expansion of the United States during the 19th century.  At 630 feet tall, the arch is covered in dozens of stainless-steel panels that gleam in the sun and create an interesting checkerboard-type pattern.  For more than 5 decades, millions of families have posed for souvenir photos at the base of this impressive monument.  Using 4 different shades of silvers and greys, this beanie recreates the subtle rectangle pattern of the arch while simple embroidered stick figures pose for a photo at the base.
