The Manly Art of Knitting got my attention because there is a cowboy knitting on the horse, besides the title. Originally published in 1972, it is a practical guide to encourage men to knitting. The author, David Fougner, lives on a ranch in Northern California where he has raise horses since 1967. And he knits, of course.
I recommend it to you, it has very interesting projects. It is a nice gift for a man who wants to get started in the art of knitting.
