Hummel Trademarks
In order for a figurine to be a genuine Hummel piece, two things are necessary:
1. Sister Hummel's signature incised somewhere on the piece:
2: A copywrite trademark from the Goebel factory,
which has changed several times since 1935.
The use of these different trademarks are critical in determining the age of the piece.
Also on most pieces there is the catalogue number of the piece,
the date the mold was created, and usually the painter's signature. As shown here:
Using these items, and particularly the Trademark, a Hummel can be narrowed down to production in certain years.
Also, the Hummel Number describes the size of the version of the item. Some Hummels were and are created in different sizes.
It must be understood there are pieces that were not always catalogued, yet have different sizes and colors.
Following is a chronological list of the trademarks the Goebel factory used and recorded.
Goebel TMK-1 (CM) – The Crown Marks
Known as TMK-1, commonly referred to as; the Crown Mark, CM, or Crown-WG.
The crown pays homage to the Imperial family, and the WG stands for William Goebel, founder of the company

These marks were used on all Goebel porcelain pieces, not just Hummel. When the size of the figurine base allowed, the M.I. Hummel backstamp was included with these marks. The mark is sometimes found in an incised circle.
When both of these markings are found together on one figurine, this is called the “Double Crown” mark.
After WWII, from 1946 through 1948, “Made in the US Zone Germany” was added.
