I love this:
Inspired by viewing Audubon’s lithographs at the 1876 World’s Fair in Philadelphia, twenty-nine-year-old amateur naturalist and artist Genevieve Jones began working on a companion volume to The Birds of America, illustrating the nests and eggs that Audubon omitted. Her brother collected the nests and eggs, her father paid for the publishing, and Genevieve learned lithography and began illustrating the specimens. When Genevieve died suddenly of typhoid fever, her family labored for seven years to finish the project in her memory. The original book, sold by subscription in twenty-three parts, included Presidents Rutherford B. Hayes and Theodore Roosevelt among its subscribers.
Only ninety copies of the original book were published in 1886, and fewer than twenty-five copies now remain in institutions and private hands. Featuring reproductions of all sixty-eight original color lithographs, archival photographs, selected field notes, and a key to the eggs and birds, America’s Other Audubon chronicles for the first time the story behind the making of this extraordinary nineteenth century book.
