Sometimes I forget that I have hard copy glass references.  I was busily searching for the name of this pattern online, with no luck, when I had an aha moment.  Aha! I have a Westmoreland reference book.  Lo and behold there was my vase in living black and white.

This vase combines the grape details of Westmoreland’s popular Panel and Grape pattern (line 1881) and the beaded edge of the Beaded Edge (line 22) pattern. You can see the one edge in the photo.

It was likely manufactured in the 1950s or 1960s.

Pieces also came with coloured decorations.  I’ve not knowingly observed one in the flesh, but from the photos I have seen, I actually prefer the unpainted pieces like this one.
