You can find vintage milk glass baby in stocking Christmas lights bulbs quite easily, but this scarce Cat in Stocking bulb is much harder to find. It's a C-6 type bulb, made in 1930s Japan, and it works. The bulb is 3-1/4 inches high, marked "SK 14V Japan". The pink stocking area has some typical paint wear, but the face is still in pretty good condition with whiskers visible.
