Very rare in good condition considering it's age. A few minor imperfections on checked side as pictured. 
Size / material label is not readable but it appears to be around M / L. The jacket has padded shoulders and measures about 23.5" length, 24" sleeves, 19.5" shoulders, 21.5" pit to pit

The jacket appears to be mostly used with checked side out and therefore shows some dirt on the solid side (bottom and cuffs). I would leave the cleaning process to professionals. Couple of issues were discovered and most of them are pictured. Please message me if you need any additional information
