Do you want vintage or modern? I have one from the 1930s (Heifetz) with a figural Pitcher as the centerpiece. It's very rare and desirable (and in remarkable NRMT condition), but I don't have the right place to display it so I could make it available. Please send me an email if you would like me to reply back with photos.
If you post this over on the Memorabilia side, you may get some other good responses as well. There are actually very many baseball themed lamps that are vintage, and can really spice up a display room. Lots also depends on how much you're looking to spend
