vintage Jewel Tea cook book, Mary Dunbar's Favorite Recipes 30s Jewel T advertising

Vintage Mary Dunbar - Jewel Tea cookbook, no date that I could see, 1930s, I think? This is 80 pages, soft cover.

This has spots from use, also a penciled dealer's note on the first page, and the name of a former owner stamped on the cover. So it's not a mint condition collector's piece, but it's fine to read or to use.
