Papua New Guinea 1972 booklet, sg SB4 - 5 each of sg212 / 213 - UMM (ref 538)

General perforation conditions can be seen in the above image. Abbreviations used in my listings are:-

(a) UMM = unmounted mint = MNH mint never hinged 
(b) MM = mounted mint = hinged mint. MM may also be used for stamps that would be UMM except for a small amount of gum disturbance approximating to a light stamp hinge effect on the gum.
(c) LMM = lightly mounted mint
(d) VLMM = very lightly mounted mint
(e) MNG = mint but no gum
(f) used = used

Please do not pay for this item until you receive my invoice. Where multiple purchases are made, my invoice will reflected a combined postage cost, taking into account the overall weight band and package size to be used for determining Royal Mail postage costs. Royal Mail UK recorded delivery / international tracked service is available if requested by the buyer, at an appropriate supplement reflecting the additional Royal Mail charge for such service.

For international buyers, please note that the weight of this item and packaging is on the borderline between Royal Mail weight bands for international airmail shipping. Actual shipping costs will therefore be sent to you when I compile my invoice - if the package falls into the lower weight band, as I hope will be the case, the postage costs will be less than indicated in this listing. PLEASE WAIT FOR MY INVOICE BEFORE MAKING PAYMENT.

All buyers with a delivery address outside the UK are responsible for paying any import duties, import taxes, value added taxes, etc levied outside the UK.
