tiny brass wine glasses, set of vintage goblets on solid brass tray Mexico mark

Set of cordial glasses or tiny wines, solid brass with solid brass tray. The tray is marked Mexico, though the goblets don't appear to be marked.

The tray measures 12 3/4" across the handles, and the glasses are about 3 1/2" tall. All of these pieces are vintage, very tarnished and in need of a good polishing.
