How do you create posters about 'product placement'?

Question

guide lines, tips, softwares, examples on how to make them

Answer 1

Were this my assignment, I'd take a photograph of some, typical, everyday scene, with several products, prominently displayed, clearly showing the brand names, sprinkled throughout the scene.

Look at how it's done in films and television. When a character is drinking a Coke, the can "just happens" to have the label facing the camera. The box of Kellogs Corn flakes ALWAYS sits on the table, facing front. ALL of the major players drive General Motors products. (The Trasformers Movie)

Set up a photo shoot with some friends and gather up containers of name brand products that will be, easily, recognized.
