Category:Duke of Portland's Audubon edition

The Duke of Portland's edition of Birds of America was sold at Christie's, New York on 20 January 2012 for a record price of $7,922,500.

It is an example of the original double-elephant folio Havell edition, one of some 200 copies completed of which just 119 examples are known to have survived. It is extremely well preserved, largely free of the excessive foxing seen in the University of Pittsburg edition uploaded in ultra-high resolution to Commons. The Christie's condition notes are as follows:

A fine copy in excellent condition, with fresh, vibrant colors. Minor defects include: some occasional finger-soiling; some occasional pale show-through from offset of succeeding plates; a few plates with moderate surface bloom or bloom-spots; occasional light discoloration, foxing or spotting; the larger plates with a few instances of plate numbers, part numbers and parts of captions being obscured by the binding, shaved or cropped; a few creases, some extending beyond the platemark; some minor tears, most repaired, chiefly marginal, a few extending within the platemark.
