Identification works best when an advertisement is treated as a manufactured historical object, not merely an image.
FormatCard, tin, sign, tray, label, package, display, premium, calendar, catalog, or fragment.
ProductionPaper, board, tin, enamel, wood, glass, ceramic, printing process, seams, edges, hardware, and construction.
ContextBrand, business, product, dealer, city, printer, address, date, original use, and provenance.
Photograph before cleaning or framing
- Full front and full back in even light.
- Every edge, corner, fold, seam, flange, grommet, easel, label, stamp, and handwritten note.
- Printer lines, patents, trademarks, form numbers, addresses, phone exchanges, and codes.
- Close-ups of ink, lithographic color, halftones, paper fibers, enamel, embossing, oxidation, paint, and repairs.
- A ruler and neutral color reference in at least one image.
Build a neutral description
“Chromolithographed card, 3¼ by 5 inches, stock image, Cincinnati merchant overprint on front, printer line on reverse, trimmed lower right” is more useful than “rare Victorian ad.”
Research order
- Determine format and completeness.
- Transcribe every word and number.
- Identify production and material.
- Research the exact company, address, printer, product, and dealer.
- Build the date range from multiple clues.
- Compare documented examples with matching construction and dimensions.
- State uncertainty clearly.
Ohio-specific clues
Look for printer imprints, bottler names, druggists, street addresses, branch stores, phone exchanges, county names, distributors, fairs, rail routes, factory locations, and handwritten family provenance.
