I don't know about your country, but in this one it is common to see a variation of this in the back window of large SUVs and mini vans. They are stick figures of a man (always the first one on the left), a woman, children of various sizes and genders, and often pets. There is so much of this around that there is a web site devoted to selling these things. I think it's really dorky.
Someone else does, too. Found yesterday on Old Main Street in St. Charles on our way to the ice carving festival.
