Shortly after taking over the business,Count Alexander von Faber-Castell developed a new range of top-quality pencils named CASTELL in 1905. 

To distinguish them from the competition, the former army officer had them painted in the green of his regiment. Under the name “Castell 9000”, the flagship product soon became a classic.

The advertising picture of the two jousting knights of the pencil was created specially for these pencils, and for decades it graced the boxes and cases in several variants.Then it was seen as old-fashioned and was withdrawn for a while. But in the early 1990's, as part of a restructuring of the company and its corporate image, the knight motif experienced a renaissance as the Faber-Castell trademark. 

In stylized form it now makes up part of the company logo.
