This is a set of cards featuring characters from both Stargate SG-1 and Stargate Altlantis. I'm only going to show the ones from Stargate SG-1.
There are 9 cards showing O'Neill. The opposite side shows another picture and the actor's name.
Likewise, there are nine cards for Carter, one of them showing her in the sexy Broca Divide outfit.
There are also nine cards for Daniel Jackson who, I think, was probably the most interesting character on the show, but since I like archeology and ancient civilizations, I might be a little biased in my judgment.
There are also nine cards for Teal'c who, in various episodes, got to wear really funny hats, especially in the episode 1969.
There are nine cards for Mitchell, who took over after O'Neill became a general. It's difficult to separate the character he plays from the character he played in Farscape, especially since Claudia Black also worked with him in that series.
Claudia, who played a character that was really interesting. Also the new general (who played the part of the President in two disaster movies), and one character from Stargate Atlantis who I liked and who was also in the series Firefly.
