Mexico has a long tradition of highly skilled sign painters, but as technology and methods of printing have changed the demand for sign painters has decreased. Centro Historico harbors a few of the last sign painters and we met one of them, “Maestro” Rodolfo Huerta. His portfolio includes gigantic hand-painted political campaign banners, murals, and paintings for contemporary artists and restaurants. Rodolfo is one of the last Maestros keeping sign painting techniques and traditions alive. He also made us a gold foil paper on glass On the Grid interpretation that took him two days to complete.
