This Moderntone Depression Glass Cup and Saucer is in the Cobalt Blue shade that Hazel Atlas named Ritz Blue. Moderntone is a pattern of molded concentric rings, each ring forming a slight ridge. The beautiful blue grows deeper as the rings taper toward the bottom of the cup.
The cup measures 2-1/4 inches tall and 4-inches in diameter across the top extending another inch with the handle. The matching saucer is 5-5/8 inches in diameter.
Moderntone in Ritz Blue was made by Hazel-Atlas from 1934 to 1942. It is not marked
As is common in vintage glassware, there are expected surface scratches but no other damage.
