When I was a new collector I saw these fairly regularly. Times sure have changed! I haven't seen one being offered for sale for some time. It’s great that some nice items finally are being listed on eBay after a dispiriting run where virtually all listings were forgettable. The RSIN for this slider noisemaker is 2 with a sustainable guide value of $150. Kirchhof made this nicely designed slider in the early 1930s. I can't think of similarly designed tin litho noisemakers, so if you don't have this yet in your collection, this item looks to be in very nice condition.
08/04 Update: This great item sold for $156.28.
