Real Photo Postcards (RPPC) (1900s–1990s)

Real Photo Postcards are actual photographs printed directly on postcard stock, not halftone reproductions.
They offer unique, one-of-a-kind views and are highly sought by collectors.

Key Characteristics:

  • Front: Continuous-tone photographic image (no dot pattern under magnification).
  • Back: Stamp boxes with brand codes (e.g., AZO, VELOX, KODAK).
  • Variety: Undivided to modern divided backs.

Dating Tips:

  • Use stamp box codes:
    • AZO: Square corners (1904–1918); triangles (1920s–1940s).
    • VELOX: Arrow directions indicate specific periods.
  • Magnification confirms real photo paper.
  • Postmarks and codes provide the most precise dates.
