Low-angle view looking up at the junction of a **red brick** wall and a **grey reinforced-concrete beam or slab edge** inside the second-floor **expansion room above the office** at the Hoffmann-Hayman factory, photographed **10 November 2016** (source iPhone 6s) — the brick in the lower field is relatively clean, with light mortar joints; the concrete soffit or beam above carries rough cast texture, board-form grain, and weathering; on the **vertical face of the concrete** directly over the brick, a **handwritten dark marker or pencil inscription in Spanish** reads **'12 de 1949 FEBRERO'** (12 February 1949), with a second smaller line **'21-52'** partly visible beneath; this **1949** mark on the structure predates the **cursive pencil** Spanish dates elsewhere in the same expansion space grouped in the 1950s (the **'Marzo' 1952–1954** sequence on the east wall, the **'FEBRERO 11 – 53'** joist, and the **'AGOSTO 8 – 56'** joist) and is consistent with a separate early construction note or roofer’s phase mark at the ceiling line, though the hand and exact intent are not yet tied to a single work crew
