There is a Ravinia connection to Botero, a documentary currently playing at the Wilmette Theatre. It is a multi-nominated profile of Colombian artist Fernando Botero. If his name doesn’t sound familiar, one of the octogenarian’s impressive, imaginative, and imposing sculptures most likely is to anyone who has picnicked on Ravinia Festival’s lawn. The Festival grounds’ Harriet and Harry Bernbaum Sculpture Walk includes Botero’s inflated form of the “Standing Woman.”
