Regional and defunct brands can offer the strongest research rewards. City directories, newspapers, trade catalogs, maps, and local archives may establish a business that is almost invisible online.
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.
