Trick or Treat bags like this seldom have more than a very modest value. Although the Hawaiian imagery is unusual, the market for these sorts of things hasn’t developed - and maybe never will. The seller has a BIN price of $111.11 but is willing to consider offers. I think $18-22 is the correct range.

4 VINTAGE 1960's HALLOWEEN Trick or Treat Bags w/Witch/Bats/Children/Skull/JOL
The secondary market has never placed a high value on trick-or-treat bags, I think primarily due to their banal imagery. This one is sure different. There is a lot going on with its undercurrent of scariness. I love the steeple and moon in the background reminiscent of the large, tooth-edged Beistle diecut of a broomed witch shown on page 150. I like the skull in the foreground and the shambling nature of the kids skirting by the old hag. This is a great TorT bag!
