Vintage MCM Glass Ashtray HOTEL ESTORIL Cascais Portugal Triangular Mid Century

A Vintage Glass Ashtray - Hotel Estoril - Cascais - Portugal Rounded Triangular Shape - 4 3/4" approximate diameter There are no chips or cracks but there is some cloudiness/discoloration. I have not attempted to clean it but will leave that to the new owner as I understand that collectors have their own special care secrets and prefer their treasures in undisturbed condition. I have read that a vinegar bath is generally used so it should be a simple fix if newer appearance is desired. Please do not hesitate to contact me if you have any questions. Thanks for Looking.
