you are not wrong. Michel confirms what you write. The catalogue does not value them though.
I believe these are cut outs from the packaging that wrapped the sheets of stamps when they were delivered to the post office from the printers.
Am I wrong?
And can anyone give me an estimate of the value please. I have been unable to find these on ebay or other platforms.
