The boy’s sister emailed me this picture a few weeks ago and I got a hoot out of it. She and her husband recently purchased a new car and she said, “In case anyone needs a Christmas idea for us, we’re a little worried about the dogs in the new car… ;)”
A quick Google search returned the Neatorama site, which claims this is a do it yourself project from an issue of Popular Mechanics in June of 1936. So with canvas, scissors, needle, thread, grommets, hooks, rubber tubing, wood, and a hefty dose of faith in your crafting skills you can have a doggie car sack of your very own. I think Hamlet will continue to ride shotgun.
