The Passing of Robin Hood, N.C. Wyeth
On Wikimedia Commons. If I’m reading the Brandywine River Museum’s N.C. Wyeth Catalogue Raisonné correctly, the original is in the New York Public Library.
The illustration is from The Adventures of Robin Hood by Paul Cheswick and N.C. Wyeth. The full edition can be found used; but you can also get the Young Readers version from the Brandywine River Museum Shop, with the illustrations printed larger than in the original.
Wyeth’s masterful control of light is what gives this moment its power.
