Gasparro drew with marker on a photograph over the image of a plaster galvano (model,) indicating propsed changes to the coin design. In the next phase, Gasparro would add detail to Libety's hair, a crown, and a collar.
The technology of Gasparro's time allowed him to work on multiple copies of the same image without having to redraw the image every time. Here Gasparro not only added marks with pencil on the Phrygian cap (Liberty cap) but also removed marks by painting over them in white-out fluid. The process was limitless, and the drawing was complete only after it matched his vision.
Gasparro used the photocopy as an intermediary step from sketch to completed drawing. By painting with correction fluid (white out) he took away unnecessary marks and lines and made a more comprehensive drawing.
Each drawing makes a change. In this variation of the proposed reverse image for a United States dollar coin, an eagle perched on a rock with its wings spread, holding an olive branch in its beak. The eagle appears to burst through the rays of the sun in the background.
