Hello wags, and thank you for your question.
The short answer is, very little!
On the web, I found one reference to Pierre Ino in a french book list.
"Pierre INO, surrealist painter born in 1909, belonged to the group
'Gravitations' influenced by Supervielle and Gonzague Frick." He,
along with other painters and poets founded the "Transhylisme" (beyond
matter) movement in 1930.
(scroll down to the "Dumont, Francis" entry)
More about "Transhylisme" can be found in a description of the book
"Physique et Methaphysique de la Peinture" (Physics and Metaphysics of
Painting) by Louis Cattiaux. See the critics' reviews for more
opinions regarding the movement.
Ino's most known work is "The Traveller," pictured here in this print.
"Traveller" by Pierre Ino (BigCanvas.com)
George Waldemar published a collection of Ino's works entitled "Pierre
Ino" in 1947, published in Paris by Éditions Galerie de Berry. It is
not obvious from the citation whether the book includes a biography on
the artist. The following libraries in the US own this book, and could
possibly be contacted to find out more.
* New York Public Library (research collection, New York, NY)
* University of Wisconsin (Madison, WI)
