These three photos are a part of Thin-Up Girls, a series of parodies of the 1940's pin-up (with a pun for a title).
Other forms of rhetoric:
irony- In the first photo, the woman is standing on a scale, while happily eating icing. The sarcasm is obvious. She is confident and unashamed; her identity is not reduced by a frivolous measurement.
allegory- In my opinion, the scale represents the suffocating pressure society places on women to fulfill a requirement of physical beauty. (All three photos contain allegory in this sense.)
hyperbole- The second image exaggerates the abilities of the model to exemplify, the modern woman. Really, is there anything she can't do?
pun- In the third image, the dom-like model is illustrating restraint; rather than a sexual theme, the restraint is applied to baked goods.
