Kruger's photographs are definitely masculine in nature, with simple bold text in very straight forward statements. There is only one sentence and gets right to the point without a lot of embellishment or frivolous adjectives and "girly" qualities. The first picture of the arm and the torch is clearly a man's arm, a quite strong and built one at that, maybe symbolizing strength of a body builder or something of that sort. It actually reminds me of gladiators or early olympic games, made all the more prevalent  with the torch, a symbol of the olympic games. The third picture is also of man hands. The texts are referring to work and business, typical man's work. and the picture of the storm and rocks don't imply feminism in any way to me as rocks and storms seem to be associated with strength. Military references always harken back to men. j

I don't see how she would be challenging men or masculinity, but is maybe just making commentary on it. I don't see how she could be challenging it in any form other than satire, which is subtle and can be over looked if the viewer is not looking for a challenge, or even a masculine reference.
