USPS Features Abstract Expressionist Painting

Even the United States Post Office is getting all arty on us! They've recently issued a souvenir sheet commemorating abstract expressionist paintings.

List of Stamp Artwork
The Golden Wall (1961) — Hans Hofmann (1880–1966)
Romanesque Façade (1949) — Adolph Gottlieb (1903–1974)
Orange and Yellow (1956) — Mark Rothko (1903–1970)

Note that the de Kooning is from The Phillips Collection. Neat!

Text on the sheet of stamp explains that the abstract expressionists "transformed the act of painting into a means of self-discovery, which was both uniquely American and utterly new." I think we've seen all of these paintings so many times that we forget that these painters were quite revolutionary.
