File:Trademark Warning - March 1927 Vogue.jpg

English: Warning published in the March 1, 1927, Vogue magazine against the use of "Vogue" with products as violating the trademark held by magazine publisher Condé Nast. Since the magazine endorsed and recommended other products, the use of the name could be inferred falsely as an endorsement by the magazine, and would thus infringe the magazine trademark. The warning request readers of the magazine to notify it if they saw such infringing use of "Vogue". The federal case noted in this warning is Vogue Co. v. Vogue Hat Co., 6 F.2d 875 (6th Cir. 1925). The title of the warning incorrectly calls it a copyright warning, although the text correctly refers to trademark.
