This hard to find 1930s glass Christmas ornament from Germany is called Santa in a Window in one of my books, another calls it Elf in Window. The 3-1/2 inch high stippled round ornament is silver with painted pink, yellow, and green details. An empty window is embossed on the back, big pine trees are embossed on each side. There's some paint fading to the trees and silvering loss near the top. When you hold the ornament up to the light, there is a semi-transparent effect from normal age degradation of the inner mercury. No chips or breaks.
