| Sketch by Longacre for the double eagle |
James B. Longacre, a federal employee in the performance of his duties made the sketch. - Scanned from page 52 of Cornelius Vermeule, Numismatic Art in America
(1971). Vermeule credits the Museum of Fine Arts, Boston. Longacre was
an employee of the Federal Government as Engraver to the Philadelphia
Mint, and so sketches in preparation for a coin are in the course of
duties.
