This striking painting is instantly recognizable as a Frida Kahlo. Roots, a self-portrait done in 1943 will be sold at Sotheby's New York on May 24 as part of their sale of Latin American art. It is oil on metal and has never before appeared on the public market. The painting was done after Kahlo remarried her Diego Rivera and is one of her few full-length self-portraits. The painting is expected to sell for $5 to $7 million.  The painting will most likely set a record for Kahlo's work and could set a record for work by a female artist.  I wonder if Madonna, a noted Kahlo collector, will be bidding on this one.
