Also known as

C. Bertram Hartman, Hartman, Bertram

Bertram Hartman (1882–1960), also cataloged as C. Bertram Hartman, was an American painter identified consistently across Wikidata, VIAF, and Getty ULAN authority records. The available biographical source describes him as working in both oil and watercolor. Public-domain works surfaced in the collected source pack include Trinity Church and Wall Street and Mark Island, indicating that collectors may encounter city and architectural views as well as landscape subjects under his name. Hartman’s work is best researched through careful matching of the artist’s name, medium, subject, and object-specific documentation rather than through an unsupported movement label. Appraisily’s artist page contains a substantial aggregate auction-record signal for Hartman, but the present source pack does not supply individual lot descriptions or a comprehensive scholarly biography. His identity and lifespan are well anchored; claims about stylistic affiliations, training, periods, or catalogue status require additional institutional or scholarly evidence.

Common works and media

Available sources identify Hartman as an oil and watercolor painter. The collected public-domain examples include an urban architectural subject, Trinity Church and Wall Street, and the landscape Mark Island. These examples support paintings—particularly city views, architectural scenes, and landscapes—as relevant work types in auction and appraisal research. The source pack does not establish that Hartman produced sculptures, ceramics, posters, or formally issued print editions, so those categories should not be assigned without object-specific evidence.

Market and appraisal context

The collected evidence supports oil paintings and watercolors as the principal work types to consider when researching Bertram Hartman at auction. Comparisons should distinguish between media and between subjects such as urban or architectural views and landscapes. Appraisily’s aggregate record signal indicates that public auction material exists under Hartman’s name, but the research pack does not expose individual sale dates, realized prices, dimensions, condition reports, provenance, or attribution notes. Those missing details prevent a responsible price conclusion from identity research alone. Any appraisal should therefore verify the physical work and its documentation, then compare it with genuinely similar public records rather than treating every result attached to the artist’s name as equivalent.

Auction categories and appraisal factors

Common auction categories

  • Oil paintings
  • Watercolor paintings
  • American landscape and urban-view paintings

Value drivers

  1. Medium and work type, especially the distinction between oil and watercolor
  2. Subject-matter comparability, including urban views versus landscapes
  3. Comparison with public auction records, sale dates, realized prices, and closely related lots when those records are available

Appraisal caveats

  • The collected pack provides an aggregate Appraisily auction-record signal but no readable lot-level descriptions, sale dates, realized prices, condition reports, or provenance records.
  • The sources do not establish a catalogue raisonné, edition history, or documented authentication authority for Hartman.
  • An object-specific appraisal requires examination of the work and its documentation; identity-level records alone do not establish attribution or value.
