The Pynchon Gallery Exhibition
is one of the few exhibitions that featured Woodward's "Crayon Drawings." As many as 13 were reported to be exhibited and this website
is not aware of any exhibit that featured more than this number. The Deerfield
Academy, 1932 Exhibition featured 10 drawings.
"The Hopper at Greylock is a fine 'close-up' of the hills, shows the depth of the distant color and the sky when the sun comes through rain clouds."
There is another chalk drawing of the "hopper" made in 1931 and exhibited at the Myles Standish Gallery in Boston named, Greylock Hopper.
"...the pastel works - they're just fantastic. And I'm afraid that they photograph very well but you don't really appreciate the difficulty of making them until you see them up close. That as you know with pastel, you have to be very very good to make it work, because it hard to correct a mistake. With oil paint it's much easier to cover over the error. But these are really really spectacular."
