Shot on a camera I now own with a fascinating family history, not by me, but by my grandfather in the early 70s. Back then doing slides was the en vogue thing to do when you traveled. Dated 1974, I can only assume my grandparents were traveling somewhere where traffic was an issue and Grandma was driving. Today we have Facebook albums for travel photos. Even before I was born, I think they probably thought they should shoot photos, not each other.
