Cork Stamp Debuts in Portugal
The world's first stamp made entirely from cork was issued in Portugal on Wednesday, in a ceremony intended to show how the cork industry is diversifying in a world of screw-top lids.
The stamp is made from wafer-thin "paper cork", with a thickness of just 0.35mm, and is the first in a print run of 230 000 - all of them unique due to the cellular structure of cork.
Designed by the Portuguese engraver Joao Machado, the stamp has a face-value of one euro and depicts a cork-tree on a hill.
