(伪造者), did well in his job that he was able to make his living for 15 years by
selling false signatures of famous Americans. Spring was born in England in 1813
and arrived in Philadelphia in 1858 to open a bookstore. At first he made some
money by selling his small but real collection of early US autographs (亲笔签名).
Discovering his ability at copying handwriting, he began to learn the signatures
of George Washington and Ben Franklin and writing them on the title pages of old
books. To reduce the chance of being discovered, he sent his works to England
and Canada for sale. Forgers have a difficult time selling their products. A forger can’t go to a respectable buyer but must deal with people who don’t have much knowledge in the field. Forgers have many ways to make their works look real. For exam A. There was a greater demand there than in America. B. There was less chance of being discovered there. C.
