"The Lunch Box"

The American Woman's Cook Book, edited and revised by Ruth Berolzheimer, published by Consolidated Book Publishers, Chicago, in 1946.

As much care is needed in selecting and preparing the food for the lunch box as for the other meals served to the family. If the lunch is inadequate or lacking in food essentials throughout the year, the individual's whole nutrition will be seriously affected, and his work will suffer. The lunch box is one of three meals, not just a "snack," and should possess the following characteristics:

1. It should be abundant in amount for a hungry, healthy individual. A little too much is better than too little.
2. It should be chosen with regard to the nutritive needs of the individual, and in relation to the whole day's food.
3. It should be clean, appetizing, wholesome and attractive.

My oh my oh my! What a crappy quaint old notion! Apparently, back in the crappy olden days, The Government allowed housewives-- mothers, even!-- to decide what food their families should be eating for lunch. 

And would you look at those Menu Suggestions! 

Peanut Butter, Bacon and Lettuce Sandwiches. 
Cauliflowerets.      Carrot Sticks. 
Hard Cooked Egg. 
Gingerbread.      Grapes. 
Milk.

Good grief! That's over 700 calories!!!!
