The Robertshaw measured heat cook book was published in 1947 and it says "The manufacture of your range equipped it with the Robertshaw Oven Heat Control to aid you in cooking the food you buy to best advantage..." So, it was published by the company that supplied the knob to control the oven. The Family fare was published by the US Dept. of Agriculture in May 1960 and cost 35 cents at that time. The coconut book was published in 1931 by G. F. corp (General Foods?), the company that makes Baker Coconut. The Arkansas Apples leaflet was published by the Cooperative Ext. Service and I think it was 1977.
I want Erin to make me the Fruit Cake below on page 48 of the Robertshaw cookbook.
