art deco all white ironstone china ashtray, old green mark Buffalo China 1920s vintage

Antique white ironstone ashtray, 1920s vintage Buffalo China with an early mark (the big B, no buffalo silhouette). This is small and plain but beautifully shaped with art deco simplicity. Measures just over 4 1/2" long. Condition is very good, some light wear but no chips or staining. Fits small guest soaps perfectly, as you can see. It would make a nice ring holder, too.
