2010 : Sri Lanka - 1000 Rupee note
Bird - Watermarked Paper

Watermark: Cornerstone plus on left, same image of the same Bird, the hanging parrot facing left on the right, flipped to face right,and put on the left of the watermark, darker than background with vertical 1000 lighter than background to its right.
The central vertical stripe with two horizontal decorative hexagons is clearly visible on issued banknote when you know what to look for as it is partly covered by printing and the security strip. Also seen on the Rs5000 and Rs500 notes, but not on lower denominations.

Image of Watermark paper without any Printing was listed on eBay Auction in 2013 April-May by a dealer in Germany with title
Specimen Watermark Paper Portals (De La Rue).
The Watermark paper of a few Countries were listed which included the 2010 Rs1000 and Rs5000 notes of Sri Lanka.

The Seller said I quote.
It is originally from the banknote designing process from DE LA RUE (in cooperation with Portals) for elaborating new banknote series.
It is NOT a cutout from a whole banknote sheet; it is a single Specimen on real banknote paper for the designing process from "the tables of the designers". Original size like the real note.
It contains the same watermarks and security features as the finally produced banknote.
You can see that this watermark is still a trial as the security stripe (which you can find on the real note) is replaced by a special type of watermark on the trial.

He said in E-mail I bought the notes on a papermoney fair from a dealer. He has contacts to De La Rue who offered him these papers.

The sheet with watermark is 215x67 mm much longer than the currency not at 148x67 mm shown above, Blank paper extends 33 mm on both

I sent a message online to DeLaRue and asked CBSL how security paper is sold on eBay, but got no reply. ends.
