R. A. Miller used the exteriors of the house and outbuildings on his property as an art gallery, nailing paintings made on board and figures cut from tin across their surfaces. In addition to a range of animals—including polar bears, dinosaurs, and rainbow-colored caterpillars—and a cast of devils and angels, Miller frequently depicted a character he called Blow Oskar. Inspired in part by the star-spangled getup of Uncle Sam, this patriotic figure was named for Miller’s cousin Oskar, also a preacher, who would drive by Miller’s house blowing his horn.
