Poked my head into the back room of the local St. Vincent de Paul, asked the guy if he gets lava lamps, since I never seem to see them there. "Got three back here," he says. Two faded Midnights that didn't sway me, and... this 1977 red/clear Aristocrat. Crystal-clear with great flow, for a low, low price! This is the first vintage lava lamp I've found in a thrift store in a long time.
