Sign materials

Neon Signs

Glass tubing, electrodes, transformers, metal cans, painted faces, and electrical components.

A vintage neon sign can be a mixture of original and replacement components. Tubing is consumable, transformers fail, wiring is upgraded, and paint is often restored. Good listings describe each layer honestly.

Research sequence
  1. Identify the exact sign format and intended use.
  2. Document front, back, edges, holes, hardware, and every mark.
  3. Compare construction with known period examples.
  4. Separate originality from condition and restoration.
  5. Use truly comparable sold examples, not just similar artwork.
