Cheval montant un astronaute sur la Lune

A surreal black-and-white documentary photograph of a [white] horse riding an astronaut on the moon. The astronaut, clad in a bulky [white] EVA spacesuit with a dark reflective visor, crawls on all fours across the dusty lunar regolith acting as a mount, facing slightly right. The horse sits upright atop the astronaut's back in a human riding posture, front legs bent to hold balance, wearing a saddle and bridle with reins hanging down. Setting: barren lunar landscape with scattered rocks, low undulating hills, and an pitch-black starless sky. Composition and lighting: centered medium-wide shot, harsh directional sunlight casting sharp high-contrast shadows, authentic Apollo-era vintage monochrome film texture, deadpan absurdity.
