Start by preserving evidence
Photograph the object as received. Record dimensions, materials, backs, edges, marks, fasteners, mounts, repairs, and provenance before cleaning or disassembly.
Use a matched workflow
- Describe the object neutrally.
- Transcribe every word, number, address, printer line, and mark.
- Identify format and construction.
- Build a defensible date range.
- Compare documented examples with the same issue and completeness.
- Separate facts, seller claims, and unresolved questions.
Document condition honestly
Record restoration, replacement, repainting, trimming, mounting, tape, glue, losses, fading, rust, chips, dents, tears, stains, and missing components. Clear disclosure protects buyers and the historical record.
Best practice: retain original backs, labels, pads, wrappers, boxes, hardware, groupings, and handwritten provenance unless a qualified conservator recommends otherwise.
Compare current collector listings
Use listings to study dimensions, backs, printer marks, construction, restoration, local imprints, and market supply. Asking prices are not completed-sale evidence.
