Just wanted to update that I now actually have thee of the Luminglas
displays! Although eBay prices are out of this world, I found all of
these either on Facebook Marketplace or Craigslist and all for less than
$50 each. A lot more reasonably priced! I remember them charging
anywhere from $25-50 back in the late 90's early 00's when they were in
Spencer's and elsewhere. If they are indeed collector items now, I may
have three chances in the future to sell if I ever grow tired of them.
