We came across this yesterday and thought you might enjoy it - an original promotional poster for Grey's Anatomy when it debuted in March 2005 as a mid-season replacement for Boston Legal. Boy, Season One feels like forever ago now!

Who knew what started out with little fanfare in a nine-episode run that spring would become such a hit. Note the tagline "Operations. Temptations. Frustrations." This is interesting as Complications was a working title for the pilot at one point.

Follow the jump for another cool Grey's poster, which the Lifetime network created and released when it won the rights to Grey's Anatomy repeats...
