APPRAISER: I see you have a set of Audubon's "Quadrupeds of North America."
GUEST: Yes!
APPRAISER: He wanted to make an edition of "The Birds of America" that the general public could afford.
GUEST: Okay.
APPRAISER: Following the success of that book, he envisaged a similar project for "The Quadrupeds of North America." And he, with the help of his sons, made a similar book with about 155 plates. Audubon died in 1851. And the large folio version of "The Quadrupeds" was first published in 1846.
GUEST: Okay.
APPRAISER: Here, ten years later, we get the edition for the people. The value of these three volumes at auction is around $10,000.
GUEST: Oh, really? Wow. That's amazing.
