I want to know the answer to the following question:
Who's art collection was the reason the Museo Tamayo opened?
All the background I'm provided with is that "The Museo de Arte Moderno (Museum of Modern Art) is a repository of Mexican artists from the 20th century, including Rivera, Orozco, Siqueiros, Kahlo, Gerzso, Carrington, Tamayo, among others, and also regularly hosts temporary exhibits of international modern art.". Is that enough to answer the question?
