This one from a group of 1965 color studies by a Robert Williamson, found together in my neck of the woods, which, happily, were very carefully kept over the years: all are gorgeous and in near perfect condition. This one was wrapped in tissue I believe since the time of its making, such that the colors are as rich and pure as its gets, as if painted yesterday. Certainly done for an art class, and with great precision and care; certainly our Robert earned an A+. This one feels like the sun shining bright over ancient pyramids! 

12" x 18", excellent condition, tempera on heavy weight watercolor paper. Blank and clean on reverse.
