Hello folks,
I sent this Mauritius worn "Post Paid" with a 2020 RPS certificate for inclusion in David Feldman's recent auction. The day before the sale, they e-mailed me to say that a collector identified it as a Sperati forgery. By an amazing coincidence, the proof sheet signed by Sperati is also being auctioned this month in Germany, and someone spotted the likeness.

There is another copy, with a distinctive curved right margin, illustrated in Mr Kanai's book, making 3 known at present. They all have the same flaws - an incorrect diagonal line of colour across the P of POST, and erosion of the inside vertical frame-line in front of the queen's face.

I have failed to find any more via a Google search. Does anyone own, or know about, any other copies? Thanks for any help.
