Joseph Breintnall made a series of leaf prints on the press of his friend Benjamin Franklin. The prints notably included both sides of each leaf and were cherished by botanists on both sides of the Atlantic. Franklin worked with Philadelphia printer David Hall, and the leaf prints became a standard feature on the backs of many paper currencies, especially in the mid-Atlantic. When Franklin embarked on his diplomatic career, Hall joined William Sellers and continued to use the botanical prints.
