I am wanting to collect some high res photos of the old ballparks 1880's-1950's. Would hope to create a collage of photos suitable for framing up a 16x20 print. The +Century mark ballpark photos are the one's I'm struggling with. While I've found several, most of the image size is too small for Adobe to work it's magic. If someone can point me to some sites to get some dead-ball era parks, I'd be ever so grateful. Here's the best photo I've found of the PoF. Hoping there are some others restored to a quality level. Thanks all

Couple of good ones on Twitter
