Starrucca Viaduct, Pennsylvania, Jasper Francis Cropsey
On Google Art Project, high resolution downloadable file on Wikimedia Commons, original is in the Toledo Museum of Art.
Given the level of detail, Cropsey’s painting of the Susquehanna River Valley, and the great railroad viaduct that spanned the river in northeastern Pennsylvania, is smaller in scale that might be assumed, only 22 x 36 inches (57 x 92 cm).
