A prettily intricate floral motif of an aster flower in each of four vertical panels in the glass decorates this hard to find Primo Yellow Depression Glass Cup by US Glass.
This unusual pattern, called Primo, was made by US Glass during the early 1930s.
This yellow cup measures 3-1/4 inches in diameter, (add an inch for the handle) and 2-3/8 inches tall. There is no mark.
It has some very minor roughness that blends with the mold seam on the vertical rib opposite the handle.
