Vintage Invisible Man Weeble

Back in the 1970s, Scotch brand tape released a series of very creative television commercials featuring the Invisible Man, who promoted their product's high-quality "invisibility" when used for repairs.
Scotch also worked with the Hasbro toy company to create a promotional Weeble of the Invisible Man: a solid black Weeble with glow-in-the-dark hands, feet, and hat.
I didn't know anyone who had one of these back when we were kids: they were scarce back then, and are consequently even rarer today. Thank goodness for eBay...
