Any Kansas City dopers care to do a Royals fan a favor?

I’ve got a collection of baseball cards of all guys who ever played for or managed the Royals or who sat dumbly in the manager’s seat (read: Tony Muser). I also have a few postcards of the old Municipal Stadium and of Royals Stadium from when it was still called that. I’d been hoping to add to my collection a more recent postcard of Kauffman Stadium, one which actually identifies the park as Kauffman Stadium in text either on the front or the back.

Do any of you pass by stores which sell KC souveniers of that sort? Any of you perhaps use the airport on a regular basis, where such postcards might be sold?

I’d greatly appreciate your help in adding such a postcard to my collection. I will, of course, pay back your efforts. Thanks.
