Harry Kitten and Tucker Mouse become friends wile journeying through New York City. Selden and Williams (often considered the dean of modern American children's book illustrators) collaborated on seven book in this series (which also featured Chester Cricket). This was one of the last of the series to be published, but chronologically it was the earliest. This is the first edition. Only minor wear on the book; the jacket has short front corner tears and wrinkling at the spine ends, but otherwise is just fine.
