Whoa! What a story! Cantinflas is the soul of Mexico; he's like Charlie Chaplin, if everybody in America still watched Charlie Chaplin every day. I never heard this story, and never saw these magnificent photos. Thank you for this.
The story is considerably fleshed out beyond the bare bones of the Kickstarter page by Googling "miriam golden ballet" (there's a different Miriam Golden at UCLA in the political science dept.) and reading the Wikipedia page on Cantinflas.
