The 500 mon in position 25 has two insect faults in upper margin which have been improved, although the position 33 is in superb condition.; the 100 mon multiple with natural wrinkling in two stamps -mentioned for accuracy-, otherwise being very fine with exceptional margins.Only nine covers, two cover fronts and one large fragment are recorded exhibiting this very rare postmark, with this remarkable combination franking, featuring a 500 mon earliest printing pair and a 100 mon block, most probably being unique.
