Early Armour Products
I'm always curious about food products from the past and my collection of advertising cookbooks provides me with a great deal of information on the subject. Had I the resources and the space, I would probably be collecting vintage product packaging along with the cookbooks.
Sometimes the illustrations in these old cookbooks and recipe booklets provide me with a glimpse of the actual products and their packaging that I wouldn't be able to find elsewhere.
Armour and Company published a booklet, The Business of Being a Housewife - A Manual to Promote Household Efficiency and Economy (1917, 60 pages) that contains several nice illustrations of their ham and bacon products and some of the products from their Veribest line of foods.
