The Potter and the Surgeon, in art and text, reflects on creation and loss. As in much of her other work, Pérez designed this book with an additional layer, one that only reveals itself upon deeper examination. In this case, she completes the pages by trading her brush for a needle, and pierces tiny pinholes in the paper. These holes (different sizes and pierced in different directions) create and complete lines. Under normal viewing, these lines and textures go largely unnoticed. When held up to a light source, however, the reader is gifted with a parallel viewing experience, where light streaming through pinholes reveals a glimpse into an unseen realm or alternate reality.
