This book has several patterns for zip-front cardigan sweaters or jackets to knit using Chinook 6-strand wool yarn.  There is a range of sizes to fit men, women and children.

It was published by Chinook and has no copyright date listed.

All of my pattern books are second-hand.  You will sometimes find a wrinkle, folded corner, margin note, old price sticker, etc., but they are all in good clean usable condition.
