New York: Self Published, 1918. Two works, offered together, on the subject of the acquisition of artworks by American museums. Both written by Edward Detraz Bettens. His mother (Louise E Bettens) had been a patron of the Fogg Museum's art collection. Each work was printed in 650 copies (un-numbered) for private circulation (it seems primarily among institutions and art buyers). The theme of each is to encourage and outline reasons for buying artwork directly from living artists, rather than through brokers. Picture Buying is the sequel, and much of it is containing responses and letters regarding the original publication. Both in green cloth, with high quality laid paper. 66, 88 pages + photographic plates. 250 by 160mm (9¾ by 6¼ inches).
