Description
Belgium 1985 - Bird by Buzin: 9F Putter with spectacular misprint and other - OBP/COB 2190-Cu
MNH (Mint never hinged)

Please have a good look at the scans.
These stamps are printed in 4-colour printing: black - Red - Yellow - Blue.
Red print: appears to be normal (but possibly also double).
Black print: very heavy, so probably double printed.
But the green part (= blue + yellow) is printed inverted (rotated 180 degrees) and also very heavy, so possibly also gold plated printing.

Registered shipping.
