A couple years ago I had this experience with the work of Harrison Cady and then after seeing his amazing illustrations that once, I have been running into them everywhere.
The stories of "Reddy Fox" are one of those free downloadable stories I ended up with on my phone and my son listens to them over and over. Then I realized that the handwork teacher at my school reads these books to her students while they work quietly.
Winsor McCay, and even Dr Seuss started working this way under the constraints of deadlines. It was a rich environment to bring up talented drawers in. I sometimes wish I could enforce that kind of pressure on myself to push myself.
Harrison Cady had a long association with Thornton Burgess, illustrating the writer's books, including Happy Jack, and his daily newspaper column, "Bedtime Stories". Their partnership spanned five decades, beginning with Baby Possum Has a Scare (c. 1912), The Adventures of Reddy Fox (1913) and Buster Bear Invites Old Mr. Toad to Dine (c. 1914), The series continued into the 1950s with At Paddy the Beaver's Pond (1950), followed by the reprint The Animal World of Thornton Burgess (1962).
