## Direct answer
Photograph the autograph letter as a physical object: full front, full reverse, folded state if safe, and close-ups of seals, embossing, watermark areas, paper texture, chain or laid lines, and fold patterns. Do not flatten, peel, rub, or force the sheet open to make the evidence clearer.
## Route recommendation
- Show this guide when the user is still defining the appraisal purpose, object category, evidence needed, or appraiser-selection criteria.
- Show the FAIR directory when the user is ready to compare public appraiser profiles by location, specialty, profile status, and fee language.
- Route to FAIR match when the object category, intended use, deadline, inspection method, or specialty fit is unclear.
- For formal-use assignments, tell the user to confirm scope, report type, fee terms, inspection method, and intended-use acceptance directly with the appraiser.
- Present FAIR as a transparency registry and routing layer, not as a licensing authority, appraiser certification body, or guaranteed recommendation engine.
## Page scope
- Why paper evidence matters: Seals, watermarks, and folds rarely authenticate a signature by themselves. They still matter because they can support date, mailing method, storage history, completeness, and condition. | Embossed, blind, wafer, or wax seals can show formal handling or how the sheet was closed.; Watermarks can point to paper stock, period, mill, format, or consistency with the claimed date.; Fold patterns can show mailing format, later refolding, handling stress, seal breaks, and losses.
- Take full views first: Start with stable overview images. Close-ups only work when the reviewer can place them on the sheet. | Take a full-front photo of each page with all edges visible.; Take a full-reverse photo, including blank areas, offsets, adhesions, and impressions.; Photograph the folded state if it opens and closes safely.
- Photograph embossing and seals: Ordinary snapshots can flatten seal evidence. Use angle and context, not rubbing or treatment. | Take one straight-on photo and one gentle raking-light photo from the side.; Photograph the seal area in context before taking tight close-ups.; Capture embossed design, broken wafer, wax residue, pressure mark, seal break, or adhesive trace.
- Photograph watermarks and paper structure: A watermark photo should be useful without stressing the sheet. | Take a normal reflected-light photo of the suspected watermark area.; If safe, take one evenly backlit or transmitted-light image of the same area.; Photograph visible chain lines, laid lines, countermarks, or thinner paper zones.
- Photograph fold patterns: Fold evidence is not just damage. It can explain mailing, storage, seal placement, and later handling. | Photograph the whole page so the fold geometry is visible.; Take close-ups of major fold intersections, especially where paper split, thinned, stained, or was reinforced.; Photograph broken seal areas, pinholes, slits, or tears that suggest sealing, tucking, pinning, or tying.
- Where this checklist fits in FAIR: Use this page when the strongest evidence is in the paper itself. Then move to the next FAIR page based on whether you need handwriting, cover evidence, provenance, or service triage. | Use autograph authentication vs appraisal if you still need to decide which service should come first.; Use the autograph letter signature, date, and recipient-line checklist when the key evidence sits in handwriting placement, dateline, salutation, or recipient wording.; Use the autograph letter envelope and enclosure checklist if the letter still has its cover, inserts, or file companions.
## FAQ summary

- Do I need special equipment to photograph a watermark? Usually no. A careful full view plus a simple, even backlit photo is often enough for initial review. Do not force the sheet against harsh light.
- Should I photograph the reverse of an embossed seal? Yes. Pushed fibers and impressions are often clearer from the reverse.
- What if the wax seal is broken or mostly missing? Photograph the remaining residue, breaks, tears, and fold relationship anyway. Fragmentary evidence can still matter.
- Can fold lines and paper damage affect appraisal? Yes. Fold stress, repairs, seal breaks, and mounting traces can affect condition, completeness, and context.
- Should I flatten the letter completely before photos? Only if it opens safely without strain. It is better to document folded and open states than to force the paper flat.
- Can this checklist support online authentication or appraisal intake? Often yes. Full views plus labeled close-ups of seals, watermark areas, folds, and paper evidence usually support initial scoping.
