Measuring 7 1/2 inches wide and standing 1 1/4 inches tall, this spectacularly designed trivet was a product of the Rival Company, best known today for their line of crockpots. Such elegant simplicity in this design. Notice that the circular lines do NOT extend all the way around but use the negative space where they almost meet. Behind the central metal circle on the back is the number 3803 most likely a shape number from their earlier line. I would put this item from the late 1930s to 1950s. It is in excellent condition as it is made of stainless steel. Add it to your Art Deco or trivet collection today.
