Zoological Society Cards

Although the company logo may not appear, keen-eyed collectors will recognize the characteristic Rotograph backs on these cards produced for the New York Zoological Society. Faulkner notes that view numbers, running in the 63000s, appear on the back of some of them. The single example I have resembles the 'D' series with its blue tint. The society name appears in an most uncharacteristic Rotograph font. If you have a number of such cards, please send a list of views and view numbers for each for listing.
