Photo of the Week - January 25, 2010
LeRue Lemer took this cabinet card photo of William G. Schooley who stands with his ordinary bicycle and in his Harrisburg Wheel Club dress. The main characteristic of an ordinary bicycle was a large front wheel and tiny rear wheel. It was also called a penny-farthing as the difference in wheel sizes resembled the differences between a British penny and quarter-penny (farthing). Mr. Schooley is in at least five photographs featuring bicycles and appears to have been an avid member of the Wheel Club. In another image, he is shown with his wife and their tandem bicycle. Photo ID: Y00909.
