Volumes 6–7 (New York, 1928–1929), complete in nineteen numbers as published in fourteen. 8vo, self-covered, as issued. 160 + 140 pages; text illustrations. Very good to fine copies. Item #6789
A complete run of the Bulletin in this format (typeset self-covered 9 by 6 inch pamphlets, saddle-stitched); quite scarce as such. Prior issues were issued mainly as stapled duplicated typescript sheets and are rarely encountered.
