Though I can't find an exact match for that stamping style, it does closely resemble those used in the 1970's to mid-1980's. As Bob mentioned, with the presence of the zip code, it couldn't be before late-1962.
Following the merger of United Press and International News in 1958, a LOT of earlier photographs were "re-released" to subscribers over the following 25 years. Many are of equal quality to their earlier counterparts as UPI still had the original negatives, but if you're hung up on the Type 1 designation, be very careful when picking up early photos with UPI stamping.
