Mystery Painting

[Danvarner@aol.com]

  I'm looking at a photo on page 168 of the Feb.1942 National Geographic in 
Chas.R. Knight's article, Parade of Life Through the Ages. The photo is a 
late 1930's or early 1940's view of the paleo hall at the U.S.Museum of 
Natural History in Washington D.C. Behind the Diplodocus mount and to the 
left of the Xiphactinus wall mount is a very large painting of what appears 
to be Camarasaurus. Does anyone know who the artist is and if the painting 
has ever been reproduced? Thanks, Dan Varner.
