Dutch printer Koninklijke Johan Enschede has produced the largest postage stamp ever printed.
The stamp, which is due to be officially presented on Tuesday, measures 60cm in length and is 49.3cm wide.
It will be registered in the Guinness Book of World Records as the largest postage stamp ever produced.
During a special ceremony, primary school children from "Het Kofschip" will place the stamp on an enormous postcard measuring 1.5m in width and three metres in length.
Het Kofschip is a school in Ouderkerk Aan De Amstel, a town near Amsterdam. The children will bring the card to a bakery, Bakkerij Out & Zoon, in their hometown.
