Antiqre Early 1920's German Accordion Noisemaker

I do not see this item's connection to Halloween. The Germans made a number of these accordion-style noisemakers, but the ones that were meant for the Halloween market have the expected iconography, lacking in this example. Given that this is merely an item manufactured for use anytime, the value is significantly below the BIN price.
