The Canada two-penny black is a famous stamp issued in 1851 by the Province of Canada. It is a small stamp, measuring only 20mm x 24mm, and features a portrait of Queen Victoria in profile. It was one of the first stamps to be printed in Canada, and it was produced using the intaglio printing process. Today, the Canada two-penny black is a rare and valuable stamp, with only about 1,450 surviving examples known to exist.
