This book is copyright 1949 by National School of Dress Design in Chicago. Each lesson has a year for the Edition. ranging from 1962-1965. Some of the pages are not bound in the book but could be by undoing the tie and restringing the pages however I didn't want to take a chance of jeopardizing the book so left that up to the next owner to decide. Some of the edges of pages are in warn condition please see photos. I don't see any signs of water damage but of course it has that old book smell. Very neat vintage book.
