Kellogg's Advertising Green 3-Spout Measuring Glass

I don't know much about this piece; I'm assuming it was part of a promotion for Kellogg's, possibly included with the sale of a product. It appears to be Depression-glass era. If anyone can enlighten me, I would appreciate it.

This is a green glass three-spouted one-cup measuring glass. No chips or wear damage noted. I've tried to show the Kellogg's name on the bottom of the glass.

Great for a kitchen collection, or a great advertising piece! (Or use it with style!)
