This portfolio of five drypoint etchings is part of a larger body of work called 'Deepening Through Clouding Over', on which Brus and Rainer collaborated. In addition to the portfolio of prints, this includes seventy-four 19th century botanical prints bearing marks and images which Brus and Rainer applied by hand. In collaborating on the prints Brus and Rainer began by making photo-etched plates of the original plant engravings. Rainer then worked on each plate first, partly obliterating the plant image with a thicket of hatched lines. The plates were then passed to Brus who responded by adding figurative imagery, often of fantastic nature. The resulting composite images were then printed.
