Forgotten Opportunity, a sculpture installation by Oliver O’Donnell, senior in the School of Art, spotlights University City’s Lion Gates on Delmar Boulevard just north of the Hilltop Campus. The original lions, created in 1909 by Hungarian sculptor Julian Zolnay, were replaced about 15 years ago with copies made from the same molds. O’Donnell’s piece — part of the 19th annual University City Sculpture Series, co-sponsored by the Municipal Commission on Arts & Letters and the Regional Arts Commission — juxtaposed new and old by placing remnants of the original lions at the base of the gates while draping the replacements in bright red velvet.
