Concord Fabric has not been printed under that name for several years. The last time I saw them as a company was probably 15 yrs ago. It was one of the groups of companies that included VIP. I am not sure if it was printed in Massachusetts or NC by Cranston Print Works or in South Carolina. It was one of the earlier companies printing fabric for quilters. I have a wallhanging made from one of their design lines which was made in 1979. It is a bit faded but still on the wall behind the couch. It was good fabric.
Kessler (especially Joan) was one of the principle designers for the company.
If it feels like one of our quilting quality fabrics then it was probably printed in Japan because it has more colors in it than the US companies were able to print.
