    Hans Brinker, or The Silver Skates went through more than 100 editions during the author's lifetime alone. First published in 1865, this replica of the 1917 edition features the exquisite illustrations by Alice Carsey, whose sensitive eye and delicate pen-and-ink lines enliven the tale of the poor but virtuous Dutch boy in a way that few other artists have achieved. This replica edition brings the enchanting work of Dodge and Carsey to a new generation of children. Author and editor Mary Mapes Dodge (1831-1905) was born in New York City. She served as editor of the children's magazine St. Nicholas, to which she attracted such writers as Mark Twain, Louisa May Alcott, Robert Louis Stevenson, Frances Hodgson Burnett, and Rudyard Kipling. She also authored the short-fiction collection Irvington Stories (1864).
