A 1793 penny found on a country road by the narrator as a schoolboy in 1913 is the link between glimpses of life of those years. As the boy continues on his way with his tin lunch-pail, he muses on how life would have been different for the boy who might have lost the coin, imagining his school, dress, food, and games. In 1913 again, the driver of a new grocery truck offers a fine knife in trade for the penny, but the boy tells how he kept it and showed it to his children and now, at the book's end, to his grandchildren. Soft prismacolor and pastel illustrations artfully blend past and present, helping to foster the sense of continuity--in places or in individuals--that the book conveys. Quiet, but nice; attractive picture-book format that may nevertheless be most useful as a young reader.
