After having fawned over it in the first Lava Lite catalog I ever got (in 1990) and loving it ever since, I finally got that elusive white/blue Aristocrat, brass, screw cap! It came from a local building salvage store; they got it from a house on which they got the salvage contract, apparently the former owner left a lot of stuff. It's clear and flows beautifully, save some air bubbles in the lava, and even has a small number of pinpoint 'stars' in the glass.
They accepted my offer of $35, but then suggested a trade, as what they really wanted was A working lava lamp (but not necessarily THAT particular one) and I brought them a spare Carlisle with a newer red/yellow screw-cap bottle. They loved it, put it in the same very visible spot the other had occupied, and they'll be running it daily. I attached a sign atop the cap reading "1977 Lava Lite. VERY hot, do not touch!"
In my opinion, this lamp in this color has an elegant appeal held by no other model. In a corner of a dimly-lit room, with the deep blue color and pinpoint holes and the elegant Aristocrat shape, specifically with the classic screw cap and the swanky brushed brass. It's a beauty, and I have it sitting off in its own solo spot.
To further the discussion: If you had to choose one model and color combo as the epitome of sophisticated elegance for evening decorating, i.e. one single lamp as part of the overall ambiance of a dimly-lit room... Which is your pick?
I imagine this in one of those late-70s living room with tan carpet and couches, and long floor-length window drapes with dim lights shining up and down from behind the wooden valances. Just sitting on a table in the corner, maybe between the couches, being a very subtle focal point, not too bright and with the sparkling pinholes.
