NY, Henry Holt, (1997). The uncorrected proof copy in plain blue wrappers (not to be confused with the more common advance reading copy in beige wrappers). This is the second issue uncorrected proof, distinguished from the first issue by virtue of a tipped-in title page that adds the ampersand between "Mason" and "Dixon" that was missing in the first issue. Small bookplate of Ray Roberts, Pynchon's editor, inside front cover. The critic Harold Bloom named Mason & Dixon as his choice for the "single work of sublime fiction from the last century." Fine in wrappers. [#028528] SOLD
