**,37 AB (20),

Charity stamp, "Olympic Week 1969", complete MNH sheet of 20 stamps in good quality in mixed perforation 9 : 11 1/4 (!)  Although two regular parforations and many perforation varieties and errors are known for this issue (e.g. double, shifted, partly imperforate) this perforation combination has not been recorded to date in literature nor is known amongst the connoiseurs. An extraordinary item !
