mod vintage black smoke formed glass tray, skeletons lizard to man evolution

Weird piece of collectible advertising with a parade of skeletons depicting man evolving from an alligator, crocodile or lizard.

It's bent formed glass, with a scales and W trademark logo at the corner. Not sure of the company of this marking. It's not otherwise signed or dated that we could see.

The glass is a translucent black smoked color, with design in white. The dish measures 9 1/4" x 3 3/4" overall. It's in excellent condition without damage.
