Interesting....if a bit weird. The full box sold quick, and I'm not surprised.
In the last two or three years a small group of Garbage Pail kids collectors migrated to Garbage Candy, and then things like Mr Bones and the other plastic candy containers of the 70's and 80's. These things routinely sold for $2-$3 each at most, and in my realm of collecting (vintage candy pieces), they're about as common as can be....but they've ramped up in selling price fantastically since 2009 or so. I find it odd and ridiculous, but you can never tell what's going to capture people's imagination.
