I have issues with the definitions, but my post was about error. If you believe the Marquard image was printed from the original negative at any time, then, in my opinion, you should not be grading or evaluating photographs for others. The error rate of the person responsible could be very high (and, presumably, one sided--copy prints will be represented as vintage prints and not the other way around).
