I have re-done the backgrounds. I tried to make 3 parks of different era's. 47 to 88 is just 88 to 01 with older signs. I put Silvam's 70's version int the 76-87 era. You,obviously, can use them however you like. I was going to do a pre-47 version as 47 is when the Green Monster was put in but I was not able to find a park of that era.
