70s Jockey Men’s Pullover Polo Medium

Vintage 70s mens pullover polo from Jockey. This appears to be a cotton or cotton blend, but the materials tag is too faded to see. I'm calling this a modern medium, but please read the measurements. There is one big, sort of unusual flaw with the shirt - under each arm, at the cuff point, not the pit, there is fabric tearing or a little hole. It looks like the cuff of the sleeve may have gotten too tight at some point and it damaged the fabric. I took pictures of each sleeve. It's not noticeable when wearing, otherwise good condition. Measurements Shoulders: 20" Sleeves: 8" Chest: 42" Length: 27"
