Picture Book of Yin and Yang Parodies of Apparitions 
(Yôkai mitate in'yô zukan, 妖怪見立陰陽画帖妖怪見立陰陽図鑑)
c. 1830
| This
  album of ten unsigned paintings of male and female genitalia in the guise of
  various ghosts and demons is generally attributed to Kuniyoshi.  The title contains a pun.  The kanji 陰 and 陽 may also be read as female and male genitalia,
  respectively.  Some of the images are similar to images in Kuniyoshi’s print series Ghost
  Stories: Night Procession of the Hundred Demons.  These paintings are not listed in in Heroes
  and Ghosts: Japanese Prints by Kuniyoshi by Robert Schaap
  (Hotei Publishing, Leiden, 1998). 
  However, four of them are reproduced in Japanese Shunga of
  Kuniyoshi by Yoshihiko Shirakura (Heibonsha
  Ltd., Tokyo, 2012).  The paintings are
  each about 10 by 7 inches (25 by 18 centimeters), a size known as chûban.  I am grateful to Robert Pryor for assisting
  with this section. |
