Vintage Aladdin electric lamp, translucent alacite glass with glass finial. This is lovely, pale green over ivory, with an art deco style floral design.
The lamp is 20" tall to the top of the light bulb socket, and 31" to the top of the glass finial. The finial looks very good, without damage. And the lamp works well, though there's a very small chip at the top near the socket.
