PICTURE PERFECT: Carolina Herrera, Francisco Costa, Narciso Rodriguez, Isabel Toledo, Maria Cornejo and Angel Sanchez will be doing a double take at El Museo’s gala Wednesday at Cipriani 42nd Street. With some artistic insight from a clutch of children from the museum’s Classroom Connections program, Ruben Toledo fired off 68 portraits that will be sold for $500 a pop and will benefit the program as well as the Amber Charter School in East Harlem. The artist approached the student-aided process like a game of musical chairs, sketching a portrait and then having the students each provide a single feature before moving on to the next portrait. He also immortalized such Latino icons as Salvador Dalí, Frieda Kahlo and Diego Rivera, and, on the celebrity front, Jennifer Lopez, Penélope Cruz, Placido Domingo, Christina Aguilera and others. This year’s bash will honor Gloria and Emilio Estefan, Ford Foundation president Luis Ubinas and Tony Award-winning composer and lyricist Lin-Manuel Miranda. Aside from pooling the underage artists, Toledo is chairing the festivities with his wife and Yaz and Valentin Hernandez.
