Children's Book Week, established way back in 1919.
When I was painting this picture, I flashed back to when my sons were small enough to fit in a wagon together. About once a week during the summer, I'd take them to the library in the wagon and let them pick out a few picture books. Then they'd play with the puppets or the computers while I picked out a bunch more for them.
When we arrived back home, I'd dump out the bag and let them look over all the books while I made lunch. It was a rare silent spell, with only the sound of turning pages as they pored over all the books, reading the pictures. Those were very happy days.
Books offer a gift that's all too rare these days -- a chance to slow down time.
