Looking for This Crochet Baby Shawl Pattern?

I am looking for a shawl pattern. The pattern was bought about 40+ years ago from F. W. Woolworth under its own brand name, but I can't remember what that was. It is a baby's shawl worked in 3 ply wool with a border. The shawl is of an open design of small squares on the diagonal. It is crocheted in one piece then a crocheted border is added. This is the basic pattern.
