An enterprising woman in my area has turned a vintage Good Humor ice cream truck into.....an ice cream truck. She has some coolers filled with ice and treats, and can be hired to drive over for parties.
There was a Good Humor man who would drive through our neighborhood after dinner time when I was young. All the kids (and some adults) would run out for a toasted almond on a stick or a lemon ice, when they heard the jingling bells coming down the street. And the trucks could be found at the town parks and ballfields on hot afternoons.
And yes, this truck still has the bells on the front.
