Just wanted to pass along to any out of staters like myself that Target seems to be selling Wrigley Field Memorabilia pretty inexpensive.
They had at my store in Stamford CT randomly a gigantic framed Wrigley Field poster for $30. I've seen similar and smaller pictures for over $100 online.
They have this matted photo of the Wrigley Field marquee that says "Cubs Win" in it for $30. It's really cool.
I linked to target.com, not sure if they're selling them online but if you're at a target I'd look for them.
