The beginnings of Zívr's sculptural work were moulded by his response to late Cubism and a fascination with the creative output of Otto Gutfreund. Shortly after prematurely leaving his sculpture studies at the School of Applied Arts in Prague (1931), he identified himself with Surrealism. The relief Head with a Seashell and a Sphere heralds Zívr’s Surrealist creations made from found materials. He combined the Cubist composition of the head with particular incongruous elements, a brass sphere and the shell of a sea animal. The artist added a poetic commentary to the art object based on the contrast of a plaster relief, a regularly shaped geometric form and a fragile organic fragment: The blue flower of the unhitched sun / brass hair / a shelled shore of shipwrecks.
