Ok, this is French. It's mid century, covered in bits.
British plate, has a stamp of Copeland & Garret, which was produced from 1833 to 1847.
I'm not 100% sure, but I think this mask is from Chiapas, although it as couple of strange marks. It's a white man with a jaguar skalp and two snakes on each side of the face.
Beauty! Pay special attention to the big blue portador de agua.
Other vintage masks. Pay attention to the mask of a man with penis nose. Probably fertility mask. Some from Michoacan, some from Oaxaca, some from Chiapas.
