The excellence of DeLongchamps’s outer Art Deco Moderne design of Fifty South Virginia is only exceed by the meticulous nature of the building’s inner details. The main entrances of the building open into interior vestibules that show more of DeLongchamps’s influence on details. The entry double doors are aluminum 12-light glass paned, the mullions of which feature a zigzag decorative motif. Decorative aluminum panels above the doors within the vestibules feature images to commemorate transportation.
The panel over the left door is an image of an early airplane, possibly Charles Lindbergh’s “Spirit of St. Louis.” Over the right door is an image of the Roman messenger god of trade, profit and commerce, Mercury. Behind each is a radiating sun motif on a base of zigzags. The vestibule is walled-in aluminum that starts on the wall at the floor level and rises to the aluminum-covered, coffered ceiling. The corners are slightly concave and feature vertical banding reminiscent of fluted columns.
A decorative cornice with vertical banding and a dentil pattern wraps the vestibule at the ceiling. Each of the three entry vestibules varies slightly in size, shape, and configuration, yet all retain the same general decorative elements. The aluminum vestibules are built into the lobby floor plan, and feature vertical banding crowned with an elaborate cornice of sunburst and zigzag motifs. Centered over the entry doors are eagles on pillars.
Except for down-folded wings, the eagles are similar to those on the exterior of the building. More zigzag patterning and a capital that features three stars decorate the pillars.
