If collectors have any one lantern in their collections it is this one. It is VERY common for a couple of reasons. This lantern was produced for many, many years. Also, a substantial quantity of true new/old store stock was discovered about 12 years ago, so finding near-mint or better examples is easy. (Generally, when a seller uses the term new/old store stock for purportedly vintage Halloween items, be suspicious.) So, with that said, this seller was lucky to get $300 for the lantern. They nearly always trade for $150, so the buyer had to be someone newer to the hobby.
