This striking cinderella stamp from the National Wildlife Federation depicts the Colorado Columbine (Aquilegia coerulea), the official state flower of Colorado. Its elegant blue and white petals are beautifully contrasted against a warm orange background, emphasizing the flower’s alpine charm. The NWF began issuing conservation-themed labels like this in 1943 to promote wildlife awareness and habitat preservation. Designed in a bold illustrative style, this 1988 reprint honors the Federation’s early efforts in conservation philately.
