Here is a Rare Vintage Retro Green padded portable Folding Stadium Seat Chair. It is from the H. S. Freed & Company. The original label is the All American Sport Seat. Patent Date from 1940. This appears to be very early edition. It has a Masonite and Wood bottom. The newer ones are metal. There are a few west sports but for an 80 year old seat…it’s in great condition.
