The smallest paper in a mahjong case may be more informative than the most decorative tile. A retailer label, copyright page, repair receipt, score card, or handwritten name can connect the object to a time and place. It can also mislead if treated as proof of the entire set.
Separate four kinds of statement
Build a research log with these labels:
- Observation: exactly what the object says or shows.
- Source: where a comparison or fact came from.
- Inference: your interpretation of the observation and source.
- Family account: who remembered what, and when that memory was recorded.
For example: “Booklet copyright 1937” is an observation. “The whole set was made in 1937” is an inference—and may be too strong if the booklet was added later.
Photograph before searching
Capture the full label, its location, and close details. Transcribe capitalization, punctuation, and uncertain letters. Search exact phrases in quotation marks, then try variants. Patent numbers, addresses, telephone formats, and company suffixes can narrow a date range, but a business may have reused packaging for years.
Keep associations intact
Do not tape a label back in place, discard duplicate score cards, or reorganize papers by size. Put loose pieces in individual, suitable sleeves or folders, record where each was found, and keep the original order. Photograph fronts and backs; handwriting on a reverse can change the interpretation.
Build provenance cautiously
Provenance is an ownership and custody history, not a decorative story. Record names, locations, approximate dates, transfers, photographs showing the set in use, and the evidence supporting each link. Mark gaps explicitly.
A useful sentence might read:
Family account attributes the set to M.R. in Cleveland by the early 1950s; a dated photograph is not yet located. The case contains a New York retailer label and a 1948 rules booklet, neither proven original to the set.
When the trail goes cold
Stop trying to force a famous maker or exact year. Preserve search terms, rejected matches, and the reason they failed. An unresolved attribution with a good evidence log is more valuable than an exciting claim future researchers cannot audit.
What belongs in a professional file
Professional appraisal descriptions commonly consider material, dimensions, maker, date or age if known, marks, condition, repairs, photographs, research, provenance, and relevant market evidence. Your log does not replace an appraisal, but it makes a later consultation more efficient.
