comments: The Aristocrat model which you see here
is especially interesting because the base and cap are painted white with
gold squiggles. This paint technique was popular with many products of
the 60s and was a factory finish.
Sometimes you'll see these bases with a matching squiggle cap, and sometimes they were sold with a solid gold cap.
Another variation: sometimes they've got "starlight" holes in the base (like the Century) but generally they're without
holes like this one. So, with all these idiosyncrasies, the Aristocrat series is bound to keep
lava lamp collectors very busy.
See the next pic for my favorite finish of all!
