This is an antique R & S Mystery Mark Espresso cup and 2 saucers. I could not find this mark on the internet. It is in very good condition, no chips, cracks or crazing.

I would really appreciate if anyone is familiar with this mark to let me know.

Cup measures 1 15/16" across top and 1 7/8" high.

Saucers measure 4.5" across.

Any questions, please contact.
