Make that two official posters for Rambo. Though I don't know exactly how to describe this style, but my guess would be er, spraypaintee.
John Rambo Poster Spraypainted
While the first poster for Rambo showed appreciation for Stallone's triceps and whatever muscles he's growing on his back, this second poster is a straight tribute to the actor. They should have, however, had 'Rambo' just say 'Stallone'. As in... Can you believe this guy is still staying fit and keeping franchises alive? Respect! (as I whip my hand)
