New discovery of one of the most important postage due covers

Hello peeps its been a while since my last blog but I have been a
 little busy working through my Chinese stamp collection. One thing
that I did want to share with you is an amazing find of a new 
discovery if one of the most important postage due covers. 
So here goes! 

One of the great joys of stamp collecting is the excitement of finding 
something new. 

You just never know what might turn up!

A really extraordinary item was recently found by staff at Stanley Gibbons 
Auctions, 
while looking through a box of material which was brought into the Strand 
for valuation. After turning over the usual nondescript hand written fdcs, 
kiloware and childhood 
albums, a spectacular large (350x230mm) brown envelope from Singapore
 was found, which warranted  rather closer inspection.

POSTAGE DUE COVER

Addressed to Major P.J. Hills in Singapore, the envelope had originally
 been posted 
without stamps, and now bore a right marginal block of  twenty (2×10) of 
the Malayan
 Postal Union 1951-63 2c deep slate-blue Postage Due with the ERROR 
IMPERFORATE HORIZONTALLY, comprising TEN (!) of the vertical pairs 
listed in the Stanley Gibbons catalogue as  SG D15ac, of which just 
one unique example (a strip of three on piece) 
had previously been recorded ! The envelope also has a block of ten of the 
1964 M.P.U. 10c on 8c yellow-orange Postage Due (SG D29), with both 
blocks neatly cancelled by the “TANGLIN SINGAPORE” cds dated 21 May 65. 
1.00pm. At the upper right of the 
envelope is an untimed “TANGLIN A SINGAPORE 10” cds of the same day, 
presumably applied on despatch or delivery.

The envelope was addressed by Mrs Hills (who must have forgotten to 
stamp it) to her husband, and has been in the family’s possession
 ever since – a little matter of53 years. This amazing new discovery,
which must rank as one of the most important  Postage Due covers 
of the entire British Commonwealth, is being offered for sale in 
the SGA  Public Auction at 399 Strand on 26 April, and worldwide
interest is anticipated, especially from the Far East.
