Large Santa head figural milk glass Christmas light bulb. It has been tested and is not in working condition. Would look nice in a display. The milk glass bulbs were discontinued in 1939, just before the War. There is surface paint loss that is commensurate with age. The Santa Claus measures about 3 1/2 inches long. Marked 15V Japan, for the C-6, 15 Volt Socket. At some time in its life someone put a tie around the top to use an an ornament on a Christmas tree.
