The St Louis Arch and city skyline with a little sparkle and glow! The silhouette of the city of St Louis, MO including the Arch. Watch the city light up after dark! It's made on stretched canvas 8x10 inches using ink, acrylic paint, glow in the dark paint, and glitter. In order for it to glow in the dark it needs to be charged by a light source such as sun, UV light, or room lights. Colors may appear a little different in person due to lighting and screen settings.
