Chocolate mould - Christmas

Heavy pewter or metal chocolate mould flat sheet tray, 10x14", featuring 3 identical images of Santa Claus. Each chocolate is 9.25" high. [Hershey, PA: Hershey, c.1940's].

A note stuck to this mould from the collector states, "Hershey - Rare." Unfortunately, that is the only identifying information I can find, as "flats" often do not contain manufacturing information. Large, shiny, bright and charming, and in fine, untarnished condition.
