So my wife was out walking the other day and she spotted this on top of a recycling bin.
It's interesting that it doesn't say "Kenner" but rather "General Mills." Without having looked it up, I'm going to guess this was part of a promotional tie-in, something you'd save up General Mills cereal boxtops and send away for... which I'm guessing makes this thing pretty darned rare.
Not that I'd ever sell it, but I am considering starting a collection of actual vintage figures, since their peg-holes are the only ones that could accommodate this thing's pegs.
