There are a couple of quick ways a collector could immediately determine this tin litho tambourine was manufactured during the 1950s. First, this Kirchhof noisemaker is marked, "Life of the Party," a mark only used during this time. Second, the colors are much brighter than the original design. (Look at the bottom of page 215 to see the original design issued during the 1930s.) The price of this older tambourine design tends to hover around $60, whereas the "Life of the Party" releases tend to bring less, sometimes much less.
01/19 Update: This brought $39.88, about the right amount.
