The definition of a Type 1 photograph according to the Yee/Fogel system, which PSA has adopted, is a photo printed from the original negative within 2 years of the photo being taken.
Given that definition, it is certainly possible, even probable, that more than one copy was made, for various reasons. The reality is likely not that many were made and some of those were destroyed/damaged/cut up for composites or editorial choices. This is why they bring premiums over Types 2, 3, or 4.
