Show moreNew York, New Haven & Hartford Railroad Small Format Photograph and Postcard Collection finding aid . The NY, NH & H Railroad Small format Photographs/Postcards Collection is a portion of the New York, New Haven and Hartford Railroad archives. This collection is distinguished from the New Haven Railroad Photograph Collection by virtue of the fact that the prints in the Photographs collection are 8 × 10′ in size and prints in the Small Format collection do not exceed a measurement of 5.5 × 3.5′. This display has led to the practical necessity of housing the two collections in different size boxes. Show less
