Lady Gaga biography promoted in your local meat case.

(click image, via) Well, in local Australian meat cases, anyway. If you somehow don't know why an ad agency (US Sydney) would place tags hawking Gaga's "Just Dance" in the meat cases of Aussie butcher shops and supermarkets, look at this. Hachette publishing is a client of the agency, so this is probably a real stunt. How widespread of a stunt is questionable. Done mostly to win shiny ad awards, not to actually sell books.
This is not the first time meat cases have been used for an ad stunt—Last year in Luxembourg markets, they were used to promote human trafficking awareness. Previously: Britney Spears Lady Gaga.
