In the early 1840's Audubon decided to paint the animals of North America. Having achieved worldwide fame with his "Birds", he joined with his son, John, and Dr. John Bachman of Charleston, S.C. to draw and describe America's quadrupeds. Like the birds, the animal paintings have no equal and are still considered the finest animal prints published in America. Audubon and his sons produced 150 folio drawings, measuring approximately 22 x 28 inches, hand-printed, and hand-colored by J. T. Bowen of Philadelphia. Each print is dated. John and Victor Audubon helped with the drawings with John being credited for many of the later plates as his father's health declined.
