But it changes the way the wall plays. These ads are raised away from the wall and are metal, thus, now the entire length of the wall has a sheet metal base molding. Also the ads were painted over in 1947 and the name green monster was born. Furthermore these ads were flush to the wall and did not change the playing characteristics of the wall, whereas the modern ads altered the feild of play. I dont like how a coroporation has influence over a matter such as this, and I think there should be a limit on advertisiments in all parks, whats to stop parks from becoming milliondollarhomepage.com
