This is an original print made by the studio for its internal use. Contact sheets are used to choose photos for distribution. They're not meant for distribution themselves, so only a couple copies of each contact sheet would have been made.
I bought this in a Heritage Auction sale in 2023. See the receipt. (It was part of a lot of 15.)
There is an increasingly collecting interest in these. For example, search for the New York Times piece from last month on "The Analog Allure of Photographers' Contact Sheets."
This will be shipped with full insurance.
