Low-light close-up on the **interior north wall** of the **first floor** at the Hoffmann-Hayman factory — a single masonry stretcher bearing the raised embossed legend **STAR BRICK** in serif capitals (the manufacturer's name-mark block), olive-grey porous clay with a faint horizontal frog line bisecting the lettering, seated in granular buff-grey mortar joints; the wythe sits below a coarse dark relieving course at the top edge of frame and drops into badly spalled and missing mortar toward the bottom, revealing rough subsurface masonry and cavities in deep shadow — readable **maker lettering** tying the site's summary language about **star-stamped San Antonio street bricks** to **in situ masonry** inside the factory's north **first-floor** interior (**interior north wall** per site documentation — **this gallery** places the frame immediately **after** the **[north-end freight elevator look-up](/assets/images/gallery/factory-downstairs-elevator-shaft.jpg)** listing); photographed **4 December 2014** (**iPhone 5**) with grain characteristic of handheld low-light capture
