This diecut shade was made in Germany sometime between 1930 and 1935. Its RSIN is 2, meaning "rare." The shade is dated to this late period due to the more cartoonish nature of the art and the use of color and shading in the backing paper. It seems to be in very collectible condition, missing only its top piece enabling it to be used for its intended purpose.
