Vintage neon and lighted signs may contain high-voltage transformers, brittle insulation, ungrounded metal cans, sharp glass, and improvised repairs. Cosmetic condition does not establish electrical safety.
Research sequence
- Identify the exact sign format and intended use.
- Document front, back, edges, holes, hardware, and every mark.
- Compare construction with known period examples.
- Separate originality from condition and restoration.
- Use truly comparable sold examples, not just similar artwork.
