There are many reasons that items such as this pamphlet should be considered valuable. In the time of its distribution, it had a practical value to the government of Canada and to Canadian citizens. The information given is still able to be applied today (how to judge meat by its appearance, proper storage, as well as various recipes) but it is as necessary as it was during the time of publication.
Today, we still value items like this, but for different reasons. There is a monetary value attached to all things, obviously, however, this one does not have an estimate. As a piece of culinary ephemera, it has value to the University of Guelph as they hold an extensive collection. This value might change depending on its condition, rarity, or cultural significance.
There is also research value. The pamphlet is filled with information regarding the dietary habits required of Canadians during the Second World War. Items like this transport historians back into the time they were made and give great insight into what was important to the people of that time.
This also shows a cultural and educational value. The war effort was very important at the time. Understanding how society functioned on the home front helps people better understand how all parts of a nation are impacted by a war. It serves as a primary source for rationing and the national struggles that came with it during World War II.
