It has come to light that the Canadian 2010 Blue Whale $10 stamp has security features that include the silhouette of a scuba diver suspended above the whale itself, which is revealed only when shone under short-wave ultra-violet light!

Canada 2010 Blue Whale Full Sheet

The Canadian 2010 $10 Definitive features the blue whale, the image being the work of master engraver Jorge Peral. This stamp was produced using a combination of two printing techniques: intaglio (for the whale in the foreground) and offset lithography (for the colours in the background). The intaglio process (which was used to produce Canada’s first postage stamp) was recently reinvented using a new, state-of-the-art laser engraving technology. The colour control markings on the left margin of a full sheet of 2 are in the shape of scuba divers.
