Marks

Synonyms: stamps, stencils, seals, labels, imprints.
On this site “Mark” is an umbrella term used to designate any visual element belonging to the entities listed under the term “Business,” regardless of the materials or tools used in marking and of the support on which it appears.
The “Marks” category therefore includes labels, ink marks (as well as stencils and rubber stamps), hollow and raised  marks (intaglio stamps, firebranding, embossing), paper watermarks, and, occasionally, wax seals.
Naturally the “Marks” designate the visual material contained in the catalogue and are specific to the market protagonists featured in the list of “Businesses.” They therefore identify at once the professionals concerned, their location and period. These marks, generally present on the support of painted and graphic works, or on their frames, bear witness to the origin, provenance, and subsequent history of the materials on which they appear.
Some marks listed in the catalogue are independent of any pictorial support or work and may originate in a range of printed sources: trade catalogues, invoice headers, letterheads, business cards, address cards, brochures, etc.
The catalogue of “Marks” also covers the specific category of “registered trademarks” (trademarks and brands legally registered as industrial property).
