An afternoon trip through a photograph album takes a little girl back through three generations of her family and emphasizes the differences that time has brought in clothing, furnishings, houses and transportation. Her questions about each period (and her mother's answers) emphasize the samenesses, too, for each little girl at each point in time had her own warm bed, her own familiar set of night sounds, and a mother to hug her before lights out— and "the sky was blue". It's a comfortable, comforting trip that almost any child is willing and able to make for himself. The pictures (in 3 colors) go from album shots to illustrations which spread across two pages. Our own day and age is presented with a bleakness in furnishings and housing that is really too extreme— even for the desired contrast.
