Yankees...patooie!
OK now that that's out of the way...there is probably some memorabilia for sale from the old stadium. I know that when Fenway Park renovates, they sell the old seats or sell pieces of the seats in other items (pencils, etc.). I think RedEnvelope has some non-traditional baseball gifts. Signals probably does too.
Here is the link to the RE baseball stuff - some is quite pricey but who knows?:

Hope that helps! Go Red Sox!
