Intricate technical drawings of vintage optometry equipment fill a black ground, with the central phoropter flanked by an array of lenses, frames, and diagnostic instruments rendered in fine white line work. The composition evokes a patent diagram, dense with mechanical detail and labeled with period typography that reads "OPTOMETRY" across the top. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
