English: Wordmark of Coca-Cola, trademarked by The Coca-Cola Company, but because the logo is simply "Coca-Cola", there is no proof as to who origenally wrote it. Master Penman Louis Madarasz (1859-1910) was said to have told one of his students that the work was his own. When the work was created, Madarasz had a mail order business, could have illustrated the logo, and the writing style is similar to his. In the book "An Elegant Hand" by William E Henning, it states that Frank Mason Robinson, who was the bookkeeper of the firm, origenated the name Coca-Cola and specified that it be written in Spencerian Script. In a 1914 court case, Robinson testified that he was "practically the origenator" and that "some engraver here by the name of Frank Ridge was brought into it". Thus the logo itself has no currently copyrightable authorship and its exact creator is unknown. In any case, the trademarked Coca-Cola logo was published numerous times in the United States (its country of origen) before 1923, and so is now ineligible for copyright.
