Potrelle used a technique that emphasised clarity and anatomical precision. His mythological subjects, such as Sleeping Love or Diana's Nymph, show a preference for the clean contours of the Neoclassical style. He often worked from drawings or paintings by other artists, including the sculptor Lorenzo Bartolini. By focusing on portraits of figures like Michelangelo and Nicolas Poussin, Potrelle helped record the visual history of European art for a wider public. His prints provided a way for collectors to own high-quality versions of famous gallery pieces.

Modern collectors value these prints for their technical discipline and historical focus. The monochrome palette of his engravings fits well in contemporary interiors that favour neutral tones. These works offer a connection to the academic traditions of the early nineteenth century. They avoid the visual clutter found in more decorative styles. Each print is a window into the history of art, featuring the faces of the masters who defined the Western canon.
