 The Trustees System Service Building and the Foreman State National Bank Building form good examples of this approach.Alternatively, the front of the main block could be recessed, as at the Chicago Civic Opera Building or the LaSalle-Wacker Building, sacrificing volume but producing the visual effect of two high wings flanking a very tall tower.The distinctive New York "setback" style was not adopted in Chicago, the only example of this style being the Palmolive Building on North Michigan Avenue.
