It is heartening to see such a rare item listed on Ebay. The pickings there have been so slim for so many months that seeing this was bracing. I've been a collector and curator of vintage Halloween memorabilia since 1988 and have only seen this Gibson lantern offered for sale one time. I bought it! (You can see it on page 42.) If you collect lanterns, this is a well-designed, interesting example of Gibson's artistry. Don't let this one go!
07/12 Update: And it didn't go quietly or cheaply! It sold for an astounding $493 after much spirited bidding. Although significantly more than current book value, it could be quite a long while before another one surfaces. Kudos to both the seller and the buyer!
