1978 marked the 70th anniversary of the Mantle Lamp company (Aladdin). To mark this anniversary Aladdin designed and manufactured 2,900 of these special lamps.
The lamp was sold only with a hand painted shade and had its own special filler cap. This was the first lamp Aladdin made that had an etched surface and a commemorative button insert. Personally, I think this is the loveliest glass table lamp that Aladdin ever manufactured and would love to se them bring this version back sans the commemorative button.
This picture shows the details of the stem and base. If ever there was a glass table lamp to bring back into production to replace the long running model 23 short lincoln rape lamps I think it is this one.
