This is a Princeton.  Limited to 1,500 prints worldwide, it is said to be the finest of all Audubon editions. Princeton actually purchased the originals and physically utilized them in the reproduction process. This print is in fact the world’s only direct-camera capture of the actual original, from which it can be differentiated by the edition number penciled in the lower left, and the Princeton Audubon seal in the lower right.

At checkout, you may request that such identifying marks be placed only on the Certificate of Authenticity, and not on the print.  We suggest conservation framing, just as you would do for an original.
