Are you a victory canner?

It's that time of the year again. Time to start planning and starting the gardens. Once again I'm going to try a canning garden, only this time I'm going for pasta sauce rather than salsa. (Well, maybe salsa too) :)

So I was searching for canning recipes, and I came across this website showing several posters from WWII to encourage home gardens and canning.

It makes me wonder though, would they be promoting the thriftiness of it if they hadn't just come out of the great depression?
