Perhaps I was the only one that immediately dropped everything and ran to the post office, but I wasn’t the only mail-sending art lover thrilled with the U.S. Postal Service’s latest stamps. In March, the USPS released a sheet honoring American “Abstract Expressionist” painters. These ten artists, some of the greatest of the twentieth century, moved the United States to the forefront of the international art scene (for the first time) in the 1950s. We have many of their works on view at the Milwaukee Art Museum.
