Paper doll collectors should be acquainted with the names Berta and Elmer Hader. They created some really lovely paper dolls for magazines in the 1920s. They are highly collectible and hard to come by.
Berta Hoerner (1891-Feb. 6, 1976) and Elmer Stanley Hader (Sept. 7,1889-Sept. 7,1973) were a husband-and-wife team that illustrated more than 70 children's books, about half of which they also wrote. Their most notable contribution to children's literature was in 1949, when they won the Caldecott Medal for The Big Snow.
