NY, Bantam, (1991). The limited edition of this collaborative novel by two of the leading writers of contemporary science fiction, both associated with the "cyberpunk" movement in the field. This is a fantasy based on the premise that the computer age started in the 1850s, rather than the 1950s, with the perfection of Charles Babbage's Analytical Engine. One of 350 numbered copies signed by both authors. Fine in glassine dustwrapper and slipcase. [#911567] SOLD
