Can I develop very old film?

Today my mother gave me my great-grandmother's old camera. In fiddling around with it, I found that it is a Kodak No. 2A Folding Cartridge Primo and that there is a roll of film inside. I doubt that the film is any good, but I was wondering if it would be worth it to try and develop it. If nothing else, I may take the film out to display with this old camera.
