Old downtown Aurora has seen better days, and the city's leaders have attempted to turn that fact around in any number of ways, one of which is the installation of public art in the area. Among the several commissions completed in the last year or so is "Ghost Trolley," by Lawrence Argent, which sits in the center island across from the Martin Luther King Library. The sculpture, executed in translucent plastic, is a flattened, three-dimensional image of a trolley appropriated from a historic photo taken when these quaint streetcars ran up and down Colfax Avenue. The context combines the best of the past and present.
