Product: 20 bound volumes of text and photogravures (images made with an engraved printing process) with 20 folio volumes of photogravure plates
Research: Curtis and his assistants
Total Cost: estimated $1.5 million
Finances: The chief means of support was the sale of prepaid orders (subscriptions) of sets of books and prints at $3,000 per set. Curtis sold only 300 of the 500 subscriptions he had hoped to sell, leaving the Project in debt. Other funds came from loans, donations, lecture fees, and Curtis's other jobs. J.P. Morgan and his family also provided substantial help.
