Wealthy hacienda owners and gringo tourists wearing sunglasses have been portrayed in carnival dances for many years. In the book Masks Arts of Mexico by Lechuga and Sayer a Viejo with sunglasses for the Veracruz carnival is shown on page 22. This particular item is one of 50 Mexican masks being auctioned off on Orange Umber. Most of these beautiful masks have been used in culture or were intended for use. Decorative masks will be auctioned off later.
Good news for you: all of the starting bids have been lowered to encourage sales in this buyers market.
