Another two stamps have been issued as part of Canada Post’s month-long series celebrating the 50th anniversary of Star Trek: one depicts Klingon Commander Kor, played by the late Canadian actor John Colicos, and another shows the Klingon D7 class battlecruiser.

The stamps – the series’ sixth and seventh, respectively – were unveiled today at 10 p.m. at the Calgary Comic and Entertainment Expo.
