To announce the theatre portion of the tall Ambassador Building, Rapp and Rapp designed a monumental arcade of giant windows along Locust Street, wrapping the corner of Seventh. Thirty feet high, these windows were richly embellished with finely detailed terra cotta in Renaissance style. Highly modeled theater masks of comedy and tragedy were featured on cartouche pier and spandrel panels. The three floors of theater offices fronting Seventh Street were appropriately distinguished by terra cotta spandrel panels featuring regal pairs of sphinxes, Egyptian symbols of power.
