My grandfather taught me generosity. He sold snow cones in Harlem. I went with him at 5 and he let me hand out the change and snow cones. I learned a lot in the couple of years that we did that.
I enjoyed doing the gag covers better than the story ones because they were usually simpler. A cover based on an incident in the plot took a great deal of staging to tell a little story that was still part of the book. And it had to make sense on its own.
