I was glad to find this salt shaker pushed back on a shelf at the New Life Thrift Shop in Glenside, PA, for a dollar. The gold band design at the top indicates vintage Pyrex and, sure enough, the actual Pyrex mark is on the black cap piece.
The classic look of the design, to me, gives this glass salt shaker both a vintage and modern look. It was fairly grimy, but it cleaned up nicely after a thorough washing. I use it often...now, just need to find the companion pepper shaker!
