This is a double page illustration from Plexus which accompanied an overview of L'Homme Qui Ramassait Les Épingles by Pierre Boulle, a short story by the author originally published as part of a collection of fictional work under the title Histories Charitable (1965), although he is probably best known for two of his earlier novels The Bridge over the River Kwai (1952) & The Planet of the Apes (1963). There is quite an amount of information about Boulle and his work online, much less so regarding the illustrator, i've searched but nothing definite has surfaced so far, unless i've somehow misread his signature, I'm pretty sure it's signed as Panos, but i've included a close-up for your perusal in the final scan ...in the meantime i'll keep searching!
