So much to see. So little time.
A telegram sent to the Tate Gallery as it prepared for its 1968 retrospective of his works read: “NO BIOGRAPHICAL DETAILS. BEGIN: BALTHUS IS A PAINTER OF WHOM NOTHING IS KNOWN. NOW LET US LOOK AT THE PICTURES. REGARDS. B.”
Sorry, I haven’t seen it before, and I tried a reverse image search but got nothing. :(
If anyone wants to see the image, here’s a permanent url.
Good luck! Hope someone can help. :)
