Painted at Port Lligat.
For this desolate, rocky landscape, Dali chose an Edwardian-type car, half-smothered by flowering plants, amalgamated with the cliff, both of which share a large aperture. Then, on the left, in paranoic style, the car image is faithfully repeated in silhouette, hollowed-out in the rocks. The aperture of the right-hand re-appears on the left as a separate rock slab, suspended like a cut-out. The picture's optical discomfort springs from the contradiction between the projection of the cliffs to the left, and the emptiness in the right-hand rocks.
