The addition of Toy Story Midway Mania has radically changed the look and feel of one portion of Disney's Hollywood Studios to suit the needs of the new attraction. This new attraction is more than just a ride building, but an entire area of the park has been given a new theme to it, based around the premise of a Pixar Studios inspired area. While the new area is wonderfully decorated and holds little resemblence to what it used to look like, nonetheless, there's still one little relic from the old part of the area that pre-dates Pixar Place.
In front of the Journey into Narnia attraction, along what is now Pixar Place, is a street sign that refers to some things that are no longer at the Studios. First and foremost, it lists the street that you are on as Mickey Avenue, which was what the street was called before Pixar Place. Mickey Avenue was of course home to the now-gone "Who Wants To Be A Millionaire - Play It!" as well as those chrome trailers that lined the street where you could meet characters like Donald Duck and Minnie Mouse throughout the day.
In addition to Mickey Avenue being home to a few attractions, Mickey Avenue also was named that in part because Mickey Avenue was themed to loosely resemble Mickey Avenue at the Disney Studios in Burbank. With that original theme in mind when the park opened, you'll notice the signs for "Animation" and "Studio Offices", which were located where the Magic of Disney Animation is today, as that entire area of the park was closed off to park guests when the Disney-MGM Studios first opened.
