"Texas Mastaba" by Christo was 1 of 13 prints commissioned by the Mobil Oil Corporation for America: The Third Century, an exhibition of major American artists of the 20th century in celebration of America's bicentennial in 1976. This is a '76 first-run lithograph reproduction of the series in great condition considering its age and unframed state! As we mark the 250th anniversary of American independence, these prints are an entertaining - and in some ways ironic - reminder of our national outlook 50 years ago! This piece, a silkscreen print depicting an imaginary pyramid of 500,000 oil barrels (reminiscent of 19th century photos showing white Americans posing with towering mountains of buffalo skulls) is particularly poignant following the last 50 years of global events with oil at the heart.
