Some of us recall when the Bell System vehicle fleet was green...boy that was cool! Here we see is what I believe was the 1938 Bell logo. (Please note that this image is reversed). In 1964 the Ma Bell logo was changed (along with new Bell Company lettering font, next to the new logo). The latter has always been my favorite! The Bell trucks remained green. Starting in 1969 their new vehicles were white, with blue and gold stripes... with their revised 1969 logo (with yet another new lettering font) for one last time.
