One of the restaurants I visited was Etta’s Lunchbox Cafe.
I don’t see any of mine but my brother had the “Speed Buggy” box, which I think wound up getting spraypainted gray and used as a fishing tackle box. And your photos look perfectly fine to me!
I remember that Tinker the mechanic on “Speed Buggy” looked an awful lot like Shaggy, but without the perpetual munchies.[;)]
