Why Numbers Can Be Reused or Misleading

If a number seems out of place for a given era, it usually comes down to three main reasons:

  1. Re-photographing the Same View (Re-issues): When a popular postcard sold out and the original view became outdated (e.g., new buildings, new cars, or road sealing), Rose photographers often returned to the exact same spot, took a new photo, and assigned it the original number (or added a letter suffix like P.4269A).
  2. Bulk Purchases of External Archives: When Rose acquired local collections—such as buying out Spurling & Son in Tasmania—they assigned entire custom numeric blocks to those older negatives (e.g., the P.123100 series).
  3. Regional Block Allocations: Photographers sent into specific regions (like interstate trips to SA, NSW, or QLD) were sometimes allocated blocks of numbers in advance, leading to slight chronological jumps compared to local Victorian releases.

Secondary Clues to Confirm Date (Beyond the Number)

When dating a Rose postcard, physical attributes on the reverse side can narrow down the era:

  • The Logo / Rose Symbol: Early Victorian cards (1913–1920s) feature a large, ornate Rose emblem on the reverse. Through the 1930s and post-war years, this rose symbol was progressively scaled down.
  • Paper Stock: Post-WWII cards (late 1940s–1950s) often used slightly glossier or thinner photographic stock compared to the heavy, matte silver-gelatin stock of the 1910s and 1920s.
  • Publisher Text:
    • Early cards: “George Rose, Publisher, Melbourne” or “The Rose Series P. [x]”
    • Post-1931: “The Rose Series Co. Pty. Ltd., Armadale, Vic.

Aispy

The “Airspy” Brand: “Airspy” was the trade name for aerial photographs taken by pioneering aviator/photographer C.D. Pratt (Charles Daniel Pratt), who produced thousands of low-altitude aerial views for The Rose Stereograph Company. Pratt’s peak aerial mapping work across regional Victoria and the Dandenongs ran from the late 1920s through the mid-1950s.
