vintage King's Crown ruby flash stained color thumbprint glass luncheon plates

Kings Crown pattern glass with ruby band - ruby stain or ruby flashed color. This is vintage Indiana or Franciscan glass rather than the antique Tiffin glassware, I think?

This lot is a set of twelve plates about 8 1/2" in diameter. These are all in very nice condition without damage to the glass.

The color is strong and very red, just a few small marks and a little scratching to the color on most. The worst is shown in the border detail close up photo.
