In 1969 the United States issued a postage stage stamp with a Grandma Moses painting’s July Fourth subject. The stamp shows a horse-drawn carriage going somewhere, but the story ends just as it is about to reach its destination. It ought to have had a picnic because it is in the original. However, the designers cut the picnic occupying the entire left foreground.
