- Issued in November 2007, this unique stamp is printed on very thinly sliced cork (0.35 mm). Printed on the cork substrate is a stylized image of a cork tree sitting atop a hill.
- The stamp brings attention to Portugal's cork industry, which provides well over 30% of the world's market for cork. Some of it's non-philatelic uses are as stoppers for bottles, fishing floats, gaskets, and bulletin boards.
