Marine Life: Sea Otter and Harbour Porpoise - Souvenir Sheet
The images featured on the stamps on this souvenir sheet were engraved by Swedish master engraver Lars Sjööblom and based on photographs of the animals. Designer Martin Mörck captures the animals on the same level both in front of and behind the water, under the water, and at the surface of the water. This issue includes elliptical perforations.
