An interesting sculpture outside the museum building. According to the website of the Smithsonian American Art Museum:

Luis Jiménez began making monumental sculptures in the midst of the Latino civil rights movement. He dedicated himself to contemporary subjects that represented a racially diverse and working class America. “Vaquero,” which means cowboy in Spanish, is one of his most celebrated works.

Jiménez’s “Vaquero” depicts an anonymous Mexican American cowboy in colorful and glossy fiberglass, a material more associated with low riders and hot rods. Jiménez intentionally titled his sculpture “Vaquero” to emphasize the Spanish and Mexican roots of this classic American icon. “Spaniards brought cattle and horses [to North America],” the artist once recalled, “and Mexicans developed the whole notion of being cowboys.” The artist thought it was especially fitting that “Vaquero” came to permanently reside in the nation’s capital, a city known for its abundant equestrian public sculpture.

Home to the Smithsonian’s National Portrait Gallery and American Art Museum, the Old Patent Office was constructed in 1838-1867 and encompasses two city blocks. The museums reopened after a major renovation from 2000 to 2006.

Best to view in "Original" because other versions resized by Pbase are decidedly unsharp.
