The Birds of America
Audubon went on to ask Martin to assist with paintings for his definitive book "The Birds of America". Over the course of five years, Martin assisted on volumes 2 and 4 the book. She was not paid for this work. Audubon credited Martin with nine illustrations, but it is thought that she contributed to at least 30. Martin also provided illustrations to John Edwards Holbrook for publication in his work "North American Herpetology".
