The master engravers Baldwin Bredell and Arthur Taylor were so adept at these techniques that in the 1890s they were actually able to make a photoengraving plate and print bills in their prison cell, using smuggled tools, chemicals from the prison laundry, extracts from fruits and flowers brought by visitors, and sunlight. At the time, they were awaiting trial for producing copies of $100 bills that were so good that the government had been forced to recall the entire issue upon which they were based. Impressed with their skill, the chief of the Secret Service helped set the men up in legitimate businesses after their release.
