Grandpa Aaron (tall and thin, who "loved to tell stories and was an expert on fruit trees"), Grandpa Nahum (wide and thick, "who loved to eat and was an expert on cows") and Grandpa Isaac (small and short, an expert on rabbits). Three elderly men who, like children, are attracted to a good story even when it’s a little ridiculous, and even manage to make it come true, to what will surely be the delight of small readers of the book.
