When I was little, my favorite book was The Wizard of Oz by L. Frank Baum. We had this ratty orange paperback version — nothing special — I’m not even sure if it had the illustrations in it. I must have read that book 5 or 6 times myself during my childhood, and my sisters had all read it too. Its popularity in our household was clearly evident: my sister Jenny and I had drawn pictures on the blank pages at the beginning and end of the book, and the spine had been reinforced several times with masking tape.
