Pictures from my Grandfather Circa 1953

[pennhunter]

My grandfather was an engineer at White Motors. I apologize if this isn't the right place for these photos, but I thought people might be interested in them and maybe I could learn something about them. My grandfather died in 1957 and my grandmother held onto these pictures, which is how I ended up with them. They are of different brand trucks being tested on a frozen lakebed in Michigan.
