A large, weathered, light-grey limestone block rests on a grey paver sidewalk in Jerusalem, Israel. The block, roughly rectangular with irregular dimensions and a heavily fractured surface, features a distinct, approximately square-shaped cavity near its upper edge. This cavity displays dark black charring and contains small debris, including white cigarette butts, indicating its use as an ashtray. A secondary, U-shaped indentation is visible along the bottom edge of the block. The sidewalk is constructed from rectangular stone pavers arranged in a stretcher bond pattern. No individuals or active interactions are observed in the scene.
