For the teacup collector, up for sale is a vintage, beautiful, delicate cup and saucer from Rosenthal.  There is a symbol on the bottom of the cup that I don't understand.  It is 715/1.  If you know what that means please let me know as I am learning about these things. 

Please see ALL photos for a more complete and accurate description.  Thank you for looking and please message me with any questions or concerns you may have regarding this item.  Thank you again.
