Vintage Houston Astros Brick Red Jersey Button Down

Vintage Houston Astros men's button down jersey. Excellent, like new condition, but no inside tag. Right arm sleeve has CITGO logo, Left arm has Texas state/star emblem. No name on back. Length shoulder to bottom is 29". Chest measures 44" (measured from armpit to armpit). Size isn't labeled, but I'm guessing it's a men's size Medium. 5 buttons, left to right. It was a gift from an Astros friend, but I'm a diehard Phillies fan so never wore it. Note: I've listed color as red, but it's slightly more maroon, text is vintage off white/tan.
