During his first solo exhibition, at the art dealer Léopold Zborowski in 1931, two sculptures were acquired by the Musée National d'Art Moderne in Paris (now in the Centre Georges Pompidou) and the Museum Boijmans Van Beuningen in Rotterdam.

He was amongst the 200 pioneers of the French Resistance – he was in the Groupe du musée de l'Homme – during the summer of 1940 and participated at the Degenerate art exhibitions.

He sculpted so La Déchirée (The Torn), which was brought to London and given to General Charles de Gaulle, became one of the symbols of the French Resistance.

Iché's work is close to surrealism and like the sculptors Alberto Giacometti and Germaine Richier inherits an aesthetic born from the workshop of Antoine Bourdelle.
