another copy

an unrecorded variant of the first edition with misimposed pages

An exceptionally rare example of an early proof copy of  the first edition, the pages in this copy were misimposed producing incorrect textual continuity.  It was apparently only in the first quire that the printers erred, inadvertently exchanged the correct texts of f.3v for 5v as well as the texts of ff. 4r for 6r. All the other quires correspond to the standard copies of the edition. Later copies would correct the misimposed first quire. That this copy survived without the first quire being replaced with the later version suggests that it was a proof copy. Depending upon when the error was discovered, the second quire of four leaves normally found in later exemplars, but not present here, may never have been included in this copy.  In any case, the present copy is an exceedingly rare and perhaps unique example of the misprinted version of this edition (compare lot 71).
