The actual committee of this shirt started in 1978 and most of the items that I have found as far as this issue was around that year, that's how I was able to figure out the year 1978, this shirt has very little usage it was probably dead stock has a couple of mild stains but not very noticeable, it probably fits the smaller size rather than the traditional medium that it was.Please see photos for the condition and measurements  of the item, thanks for bidding. After 3 days of auction won or best offer received payment is expected, if you need additional time Please let me know, after that timeline i will relist the item
