Cheshire Mog has pointed out that a book exists which has examples of tornography and the description confirms it is related to impressing wax seals:
SHARP, Granville. THE GILBART PRIZE ESSAY on the Adaptation of Recent Discoveries and Inventions in Science and Art to the Purposes of Practical Banking. London: Groomridge, 1854. 8vo, engraved portrait-frontispiece and an engraved portrait of the author, numerous plates, specimens and articles, 1 torn, index tabs torn with loss. Contemp. green half morocco, gilt. Very good, uncut copy. $1500. ¶ Third edition, the only illustrated version. The illustrations, numbered through 90, but with many bis items (some folding or consisting of two leaves), preserve an extraordinary collection of inventions, many represented by actual specimens, including security paper, banknotes, checks and ink specimens. This copy apparently lacks four specimens. There are also 15 wax seals mounted on the rear pastedown illustrating the new process of ‘tornography.’ Sharp, an accountant in the East of England Bank at Norwich, won the prize of £100 for his articles applicable to banking. Cotton & Little p.52.
