I'll pass this along because I figure you all will like it and it's pretty neat stuff.
Summer Anne Burton, an artist from Austin, has a website called Every Hall of Famer, where she's posting her work. You can see some examples above.
I think these are just great and encourage you to stop by her site and maybe even purchase some of her work. It looks like she does requests.
Hat tip to keystone at Baseball Fever for passing along the information.
