Heaven and Hell copy F, plate 21. Relief etching, 15.3 x 10.8
cm., 1790, color printed and finished in watercolors and pen and
ink c. 1794. Pierpont Morgan Library, New York. PML 63935. Detail of embossment of relief
lines into the paper, caused by pressure sufficient to print from
the shallows and relief simultaneously, and of the fine white lines
between shallows and relief lines caused by the paper not picking
up the color from the escarpments between relief plateaus and etched
valleys. |
