The view from the top of the Ex-Convent of the Virgin of the Nativity, (mid-16th century) in Tepoztlan, Mexico, where Karen lived in the 1970’s, is spectacular and the top of the wall on the rooftop with the CLOUDS IN FLIGHT (NUBES EN FUGA) inspired Sergio to add it to the series. The BANCO NACIONAL DE MEXICO chose this and another WALL for their collection.
