This is a Zenga poem/painting by the author of the classic Zen Flesh, Zen Bones with the accompanying inscription written in English. It is asking, "Who did this fish painting?" "Who is Reps?" "Where is this fish going!" The painting is sealed with a chop reading "empty."
Paul Reps (1895-1990) studied Buddhism for many years in India and Japan. A renowned poet, he was largely responsible for introducing the haiku form into English, along with poem/paiintings. Reps was author of many books.
