Original vintage newspaper advertising media trade magazine ad for NEW YORK MIRROR.  The Red Rag and the Bull.  All the world knows that red infuriates a bull.  The only trouble with the theory is that bulls are colorblind.  Prof. Thomas N. Jenkins of New York University and Prof. G. H. Estabrooks of Colgate University have proved it and famous matadors agree.  We are up against the same sort of thing every day in our contact with advertisers.  They know so many things about the Mirror that simply are not so.  Cut out the worship of nonsense.    Old 1947 antique newspaper advertising and printing industry advertisement, would display beautifully matted and framed.
