This is Spinnerin His and Hers. I believe the time period is early 1960's. I would give you more details but I am not up on my advanced roman numerals.
This book is 55 pages with most of these patterns being reallty good, both the men's and the women's. If you are a pattern collector like myself you know that many of these books will have a few lulus in there for lack of a better word. This is a good set and the mens patterns are loose fitting. Great book in Mint condition.
