Unknown footed bowl with teardrop and circle pattern

Description	:	Unknown footed bowl with teardrop and circle pattern. It is 7 inches wide x 1-3/4 tall. There is no glow to it under blacklight and there are no mold lines. It resembles Thumbprint on Spearpoint (Cambridge and Dalzell,Gilmore & Leighton) but is probably from the late 1920s-1950s. Jim W
