Vintage Varsity Letter Track and Field Green S Athlete

Description

Very cool vintage varsity letter for track and field.  It is a dark green S, and am unsure what school it came from.  It has a track and field symbol patch sewn into it, and would make a great décor item.  It would be awesome for any sort of sports crafting project as well.  I believe this is quite old based on the look of the back.
It is in good vintage condition with some staining on the white parts as expected with age.  Please see all photos for exact item condition.
It is approx. 6.25" by 4.75"
