This is The Boston Cooking School Cook Book by Fannie Merritt Farmer, 6th edition; Little, Brown and Company, c. 1939.
This hard back edition features 838 pages of recipes along with 26 pages of fabulous advertisements. From Gulden's Mustard to Ocean Spray Cranberries, these classic early ads are just so much fun!
There are stains on the exterior edges of the pages and there is a slight warp in the cover. Aside from that, the pages inside are smooth and clean. This would make a great addition to any vintage cookbook collection.
