Here's an interesting item. I know nothing about it and hope that someone out there can provide more information. My best guess is, it's a flyer promoting a baseball themed USO show and involved players touring Vietnam. It looks like players from the Orioles and Pittsburgh Pirates were involved. There is a date written on it, 26 Nov 1970.
Any other thoughts or information is appreciated.
