Before recording the exact reproduction of a signature on the pen, Bushong rehearsed and drew it backwards and forwards.
His first work, a set of pens and mechanical pencils, was presented to Calvin Coolidge when he visited Black Hills. And that was the beginning of the long cooperation with Sheaffer´s. Dana claimed that a professional forger taught her tricks that gave her speed and precision in reproducing signatures.
Bushong autographed more than 40,000 copies and did so for some of the world leaders, three US presidents, and members of the Supreme Court. In addition to these, many, many government officials, business executives, and individuals of social prominence.
