Ceiling plaster

From page 33 in Luellen, Mark C. (1992). The Decorative Work of George Herzog: 1851-1920. (Masters Thesis). University of Pennsylvania, Philadelphia, PA:

A design of the Library Ceiling, the Banquet Room ceiling and the Restaurant are the three known renderings for the interiors at The Union League. The Library ceiling, 1881-882, was a geometric design, composed of many Egyptian revival style motifs. The rendering illustrates one-quarter of the square ceiling with the central sectioned-octagon outlined entirely. The design was composed of muted brown, olive, yellow, and blue. The geometric composition is decorated with scrolls and leaves. In a triangle at the corner of the design is a profile of an Egyptian pharaoph.
