One word, Masks, there is probably not a place in mexico city or the whole country or even world that has as many masks as this place (for sale), because I'm sure someone has a large collection.
This place orders to native producers of masks around the country, they have masks made from top quality wood and also cheaper, no single mask is equal to another.
Family owned, even though its a business they treat each mask as part of a personal, collection, if lucky you will find the great nephew of the founder, although he seems to have a serious character he will get to the info once you show interest.
Although its not tricky to get there, people will not recommend to go there on your own specially if you arent familiar with the area, i recommend to take a taxi or an uber.
A must if you are into art, masks and all that jazz read more
