There are LOADS of examples here (48 at time of writing) --> you need to flick through them and choose a few as your examples for the exam. Of course this does not preclude your finding your own - this is just to get you started!
I've put a lot of older ads in here to get you thinking about this idea of postmodernism as being something modern - intertextual, parodic, anarchic texts have been being made for quite a long time now - check out the Boddingtons or Carling Black Label ad campaigns for example....
