Thermometers and Clocks

Thermometers and Clocks must be identified as a complete physical format before its artwork or brand can be compared. Store thermometers, wall clocks, regulators, novelty clocks, and branded instruments.

Begin with neutral description

Write what is physically present before repeating a seller’s date, rarity, or originality claim. Include the entire object, not only the illustrated face.

Evidence checklist

• Record exact dimensions and completeness.
• Photograph the full back, edges, folds, supports, and hardware.
• Identify printing or construction before assigning a date.
• Separate original use from later framing, mounting, repainting, or repair.

Condition and alteration

Record fading, stains, folds, tears, losses, trimming, tape, glue, mounting, repainting, touch-up, replacement parts, rust, chips, dents, missing pads, and incomplete packaging. Restoration may be appropriate, but it must remain part of the description.

Research and comparison

Search exact text, addresses, printer lines, dimensions, product names, slogans, and dealer information. Compare museum, library, archive, auction, and marketplace examples while keeping object type and completeness matched.
