Graflex Cameras, Catalog 1-50M-6-33 with Supplement 5M 4-34 1A, Folmer Graflex Corporation (Rochester, NY), copyright 1933, supplement dated May 1, 1934, ~5½"x8½", 28pp & 8pp supplement
This catalog is copyrighted 1933 on page 28; it also has a coded description "1-50M-6-33", which probably means it was published in June, 1933. But there is an 8-page supplement glued in, which can be seen in the images to be slightly smaller than the main catalog. The supplement states "Prices herein are corrected to May 1, 1934" on page s1, even though it is also copyrighted 1933 on page s7. It is coded on page 7 "5M 4-34 1A", which probably means it was printed in April, 1934. Since the catalog contains no prices, the supplement is necessary to convey the pricing.
