I remember when Sears carried fabric. I have the OP's fabric as well as a lot of others from that era. When we were making custom quilts, we would show the customer the Concord fabrics swatch folder and they could pick fabrics from that. That was about all that was reliably available.
I have to say, being a dinosaur, that I still like the old fabrics and colors, can't get excited about a lime green and gray quilt, or a lot of the other modern color combinations. Hope I didn't offend anyone.
