This is a really neat lenticular advertising square for Alka Seltzer. Made by the preeminent maker of lenticulars, Vari-Vue back in the 1960s, it features Pron-Tito with his whole body moving - legs and arms and head and he winks at you, too! The glass appears with an Alka Seltzer tablet in it and bubbles and musical notes come out of the top of the glass! This is a fantastic example of the Vari-Vue effects!
On the back, it reads,
VARI-VUE® PAT. NO. 2,815,310
MOUNT VERNON, N.Y. * MADE IN U.S.A.
Obsequio de Pron-Tito means In Honor of Pron-Tito.
The piece measures 1-1/4 inch by 1-1/8 inch.
The second picture shows the transition from no glass to a glass.
We've seen these advertised on eBay for up to $35.00 each! Or, with a pin on the back for up to $40.00!
