E-hon or Ehon is the Japanese term for picture books. It may be applied in the general sense, or may refer specifically to a type of illustrated volume published from at least the mid-Edo period onwards, often as chapter-books in series. E-hon were traditionally produced as woodblock prints on thin washi paper (printed on one side only, then folded in half, creating a "leaf" with printing on both sides), bound together (right-to-left page order) with a simple external threaded binding; typically black (sumi) ink on white paper, often with polychromatic cover designs & sometimes with (usually more limited) internal colouring. Extremely popular during the late Edo-Meiji era. The modern Japanese manga format was created as a combination of ehon chapter-books with western-style comic books. See "E-hon". Wikipedia.
