Here's an audio slideshow on the SoundSlides' platform by photographer Chico Sanchez with the audio production by Leslie Mazoch titled The Island of the Dolls.
The island of the dolls is in the heart of the Xochimilco's canals, and has an unusual history. It is said that since the early 1950's, Julián Santana Barrera began collecting discarded dolls. He lived on this tiny island amongst the canals of Xochimilco and according to his family, these dolls kept evil spirits away.
The 1990s saw a program to clean up the canals, and Mexican style boats called trajineras vied its canals.
I posted quite a number of Chico's slideshows on this blog. One of the lastest was The Virgin of Guadalupe found here.
