Cabinet cards are a kind of photo portrait mounted on cardboard that were popular in the late 19th and early 20th century. Noted vernacular photography collector Robert E. Jackson not only has a slew of terrific cabinet cards, but he's also interested in how contemporary artists are painting on these old artifacts to transform them into fantastic new works. Over at House Of Mirth, Robert posted some of his favorites. Image above left by Mike Wellins; right, Colin Batty. "The Altered Cabinet Card"
