Lot of 20 Vintage 1960's Fabric Sample Squares

Beginning to list fabric I picked up from the old sewing factory. These are sample squares. In total I have around 60 or 70 of them. They measure approx 14" x 17" but have rivets at the top to go on a sample reel. Photos of names taped on the back seam. All are circa 1960's/1970's but look to lean more towards the 60's.
