Did Campbell's soup cans used to be bigger?

Reason I ask, I'm using a recipe from a 1979 cookbook. It calls
for 1 can of cream of mushroom soup.

Do I need to use more than one can?

I believe soup cans used to be bigger. I know there are other brands besides Campbell's but I think that's a pretty good yardstick to use.

1. Good question...

2. I think by an ounce or so... I'd still go with the original quantities, though...

Most of those recipes had so much in them, I'd doubt you'd notice a small decrease in one ingredient over another.

3. I have a cookbook from that era that says 10 3/4 ounce can of Camp. Soup

I think they are the same size now.
