Approximately one-third of the frames in the Senate Collection are Rococo Revival. Typically this group displays a wide-arched, ornate crest embellished with bold S- and C-scrolls, and foliage surrounding a large center cartouche, or crest. Another common configuration has a wide-arched crest with double S-scrolls enclosing an undulating line of oval cartouches that extends horizontally and flanks the center cartouche. Common cartouche themes found in the Senate Collection include: naturalistic formsmorning glories, shells, cupids, and female heads; patriotic themesflags, eagles, and U.S. shields; or plain ornament formed by C-scrolls. Contrasting these crests, the frames have rather plain side and bottom profiles.
