Here's Fenway, mostly based on photos from the internet. I put as many ads as I could in the right places, then randomly placed the rest.
I made the CITGO sign, the Covidien logo, the MasterCard logo, the Stanley logo, Beth Israel jumbotron logo, National Floors Direct logo, Hess logo, Ace Ticket logo, and the three Monster Seat logos (AAA, Sports Authority, Volvo).
Pretty much all the other ads were taken from Smokey12's Fenway from last year, including most of the ads around the upper deck and lower deck, and most of the ads on the Green Monster, as well as the Majestic billboard outside the park.
There are a few things I still need to fix; most notably the white border is missing over the lower Monster ads. I also have to figure out which file to add the Stop & Shop logo to (Smokey12 has it on the old Fenway, but the files are in different spots from last year).
Just copy the stadium_bor.iff file into your main directory.
