This is for a set of (2)  antique porcelain bottle caps/ stoppers from the Pre-Prohibition era. They are marked John Rapp & son, S.F.  The logos on these are very crisp and clean with great lettering.
Please see all the pictures for a better description.

The pictures are on a 1 inch grid to give you a better idea of their true size.

All of my salvaged items are sold in "As Found" condition. I do not clean or alter these items in any way. I feel it is best for you the buyer to clean, polish, paint, sand, or do as you wish with them.  Washing and scrubbing can also alter the vintage, time worn appeal and overall patina of a vintage item. I will leave up to your discretion
