Raw, adjective: 7. brutally or grossly frank: a raw portrayal of human passions
One of my favorites: Andrew Wyeth, "Christina's World," 1948. Love the starkness, the period feel, the way you can feel the wind blowing. And the open sky and twisting grasses remind me of the prairie.
Incidentally, the Wyeths hailed from the southeastern part of Pennsylvania, not far from UD. Wish I would've spent more time digging into the collections while I was there.
