One February morning in 1939, artist George Rickey and a group of four men met at the Selinsgrove, Pennsylvania Post Office. With cloth-covered rolling pins they attached Rickey’s mural, Susquehanna Trail, to one of the lobby’s end walls. After six hours, the entire 9-foot white wall was transformed into a spring day in the nearby valley. Two farmers, one planting and one plowing, dominate foreground. Behind them are the farmer’s family, another farmer on a discing machine and some distant buildings, including Shriner’s Church, a local landmark. The colors are pure central Pennsylvania: verdant green and chocolate brown fields, rich red earth and the blue Susquehanna River in the distance. The mural could be an illustration for “America the Beautiful,” with its spacious skies and purple mountains and farmers preparing for future amber waves of grain.
