This is a set of five matching salt dips/cellars.  They are iridescent off-white on the inside, and gold on the outside.  Simple and elegant.

Marked on the bottom with a wreath, inside of which is the word "ROYAL."  Underneath is the word "AUSTRIA."

On most of these salt dips/cellars, the letters "O.& E.G" are on top of the wreath.  On one of them are letters that appear to be CND.  Maybe these are the initials of the painter of these salts?  I do not know why these letters are different.  I have that in a close-up (although I wish I could get a much better close-up).

This company was active from approximately 1889 to 1918.

I found these at an estate sale years ago, and loved them.  I have stored them carefully in our non-smoking, but pet-friendly, home.

Set of five in excellent condition.  I see a tiny, light scratch here and there, which would be normal wear in something that is a hundred years old.
