The Fossil Hunters
is a painting by Edwin Dickinson, created between 1926 and 1928. Its claim to fame in the history of art is that it was accidentally hung sideways first at the Carnegie International Exhibition of 1928, then subsequently at the Pennsylvania Academy of Fine Arts and at the New York Academy of Design, where it received an award. Finally someone noticed that it was incorrectly oriented (according to what Dickinson said was supposed to be the right-side up).
I think it looks better on its side (below). At least, I can kinda make some sense out of the painting from that angle. But then, who said art was supposed to make sense!
