Stilwell is one of my favorites. She could draw children as no one else could, and make her illustrations into paintings. This is a full pager entitled In October from Scribner's Monthly Magazine for October 1905. The bright-eyed stare is precious. I feel certain it was drawn from life, probably with photos as a backup.

I believe it's the way Howard Pyle (1853-1911) and his pupils worked. Draw as much from life as possible and rely on the photos for what you might have missed after the models have left the studio. Not a lot has been recorded about Stilwell. We know she entered Pyle's studio at Drexel in 1898 and studied there and at his summer school at Chadd's Ford PA, moving to Wilmington DE when Pyle returned there.
She freelanced her illustrations for major publishers from 1900 while continuing to be mentored by Pyle. She eventually married and settled in Philadelphia, where she remained all her life.
Stay tuned for more of her wonderful work.
