Hot Wheels Wendesday Hot Wheels Jacket Boys Size Large By Taylor Jackets Made in USA

picked this up in Long Beach for $8. Can't find any information so I need to use the scientific of method of guessing. And my guess it comes from the classic redlines era of 1968-1972. It was made by Taylor Jackets and was made in the USA. Not sure if it has the Union label. It does seem to be a stylish jacket and it is lined. Much better than the wind breakers common at the time.
It is a size large which would be about a boys size 16 which should have fit on my mannequin better and according to my measurements it should have fit. Perhaps some bunching over the vintage shirt.
