Essley, Roger
Jon is spending the last day at his grandmother's cottage. Before she takes a nap, she tells Jon to look at some old photographs from 1915 To Jon, the photos are dull, gray, and gloomy. Jon hears some voices and falls into a photograph where he meets Paul. Where Paul sees colors, Jon sees gray. The two boys share some adventures as different photos come to life. Finally, Jon sees the color in the photographs, and finds out that Paul was his great-grandfather.
