For collectors of authentic Goebel M.I. Hummel figurines, the bottom of the piece is just as important as the artistry on top. The factory backstamp—commonly referred to by collectors as the "TMK" (Trademark)—is the chronological code that tells us when a figurine was crafted and hand-painted in Rödental, Bavaria.
Since the first figurines debuted at the Leipzig Trade Fair in 1935, W. Goebel Porzellanfabrik updated its base mark at key historical milestones. Understanding these shifts from TMK-1 (The Crown Mark) to the modern era is the key to dating your collection, spotting rare pre-war and 1950s Full Bee editions, and appraising estate finds.
Quick-Reference: M.I. Hummel TMK Dating Chart (1935–Present)
Use this chart to date any M.I. Hummel backstamp at a glance, and click any badge to inspect authenticated examples from that trademark era in our vault:
TMK-1: The Crown Mark (1935–1949)
The story begins with the Crown Mark. This earliest trademark features a stylized crown with the letters "WG" (for William Goebel) intertwined beneath it—often appearing as both an incised stamp in the clay and an underglaze ink mark ("Double Crown"). Because these pieces were produced before or during World War II, they are extraordinarily scarce. When you hold a TMK-1, you are holding an artifact from the very first years of Sister Maria Innocentia Hummel’s collaboration with master sculptors Arthur Moeller and Reinhold Unger.
TMK-2: The Full Bee (1950–1959)
In 1950, Goebel introduced the famous bumblebee to honor the artist herself; "Hummel" means "bumblebee" in German. The Full Bee mark features a detailed, dimensional bee flying inside a "V". While collectors note subtle late-1950s transitional variations (such as the "High Bee," "Baby Bee," and " Narrow V"), any 1950s "Bee in a V" is a prized mid-century treasure celebrated for its warm, hand-mixed pigments.

TMK-3 & TMK-4: The Stylized Bee and Three-Line Mark (1960–1972)
As the 1960s arrived, the logo became cleaner and more graphic. The Stylized Bee (TMK-3) features a simplified circle-body bee with triangular wings inside a "V". During this same era, the Three-Line Mark (TMK-4) debuted, stacking "© by W. Goebel" and "W. Germany" in three neat lines alongside the bee and V.
TMK-5: The Last Bee (1972–1979)
By 1972, the logo evolved again. The bee-in-V became smaller and was perched directly atop the printed "Goebel" name, nestled between the letters "b" and "e." Collectors affectionately call this the Last Bee because it was the final time the classic bee-in-V would appear on the base for the next two decades.
TMK-6: The Missing Bee (1979–1991)
In 1979, Goebel removed the bee and the "V" entirely, leaving a clean block mark reading Goebel / W. Germany. During the TMK-6 era, master painters routinely hand-signed their initials and painting dates in black or red pigment alongside the blue factory decal.
🏛️ Curator’s Note: The mid-century TMK-3 through TMK-6 trademarks represent the beloved "Classic Era" of Goebel production, admired for their velvety matte finishes, soft pastel shading, and expressive facial brushwork.

TMK-7 & TMK-8: The New Crown and Millennium Bee (1991–2008)
Following the reunification of Germany, the "W." (West) was retired. TMK-7 (1991–1999) reintroduced a small tribute version of the original 1935 crown next to the Goebel name. In 2000, TMK-8 (The Millennium Bee) debuted, featuring a large, joyful bumblebee soaring above the Goebel script to celebrate the new millennium.
The Modern Era: TMK-9 to Today (2008–Present)
When traditional Goebel production transitioned in 2008–2009, Hummel Manufaktur carried the Rödental workshop forward. Modern marks (TMK-9, TMK-10, and TMK-11) incorporate the M.I. Hummel signature, a flying bumblebee, and "Manufaktur Rödental" or "Handmade in Germany" inscriptions—often crafted in very small edition runs.
🏛️ Curator’s Note: Figurines stamped from TMK-7 to the present day belong to the "Modern Era," featuring crisp sculptural detailing, limited-edition Century and Moments in Time releases, and vibrant contemporary color palettes.

Why Your TMK Backstamp Matters
For any collector at BuyHummels.com, knowing your TMK is essential. Earlier marks (TMK-1, TMK-2, and TMK-3) and low-production modern marks (TMK-9 and TMK-10) frequently command a premium due to their scarcity. Next time you pick up a figurine, flip it over—you might be holding a rare chapter of Bavarian porcelain history!
