Art Deco logo for Riverline Labs with a geometric skyscraper silhouette against a rising sun, featuring green and black stripes.

Design a single master logo for RIVERLINE LABS in a 1920s–1930s Art Deco poster style. Use custom Art Deco letterforms, not modern serif or Trajan-style fonts. Typography must be tall, condensed, architectural, with sharp wedge serifs, stepped internal cuts, vertical spines, and thin horizontal crossbars—similar to classic theater marquee and WPA-era lettering. Letters should feel constructed, not decorative. The logo centers on a geometric vertical spire formed by bold converging lines, symbolizing alignment and inevitability. A warm orange-to-gold sun halo sits behind the spire as a secondary element. Green and black parallel stripes radiate outward, reinforcing structure and direction. Composition is symmetrical and disciplined. Cream paper background with subtle vintage grain. Limited palette. Clean negative space. This is a master mark only — no variants, no icons-only, no alternate layouts. Focus on proportion, geometry, and typographic construction. The result should look like a finished vintage poster logo that could be reconstructed in vector. Mehr sehen
