Very similar to the "Weather Comfort" book, yet smaller in size. It has a lot of the same information and pictures too. It was released to commemorate the 100th anniversary of the first Barbour catalog in 1908. The cover is a reproduction of the very first catalog, which was only 12 pages.
It's a nifty little booklet and there are some scans of it out there on the interwebs, if you look. I'll put some up, of course, after I fix my scanner.
