There were advertisements during early 
            1900's promoting the realism of the talking machine. 
          But in the 1908 "Which is which?" 
            advertising campaign by The Victor Talking Machine Company the question 
            was directly asked of consumers: Can you really tell the difference 
            between the actual performer and the Victor record?
          The "Which is which?" text 
            was graphically positioned between an artist and a Victor machine 
            followed by the answer that "You think you can tell the difference...But 
            can you?"
          Examples then followed of various venues 
            where listeners were "delighted" where they thought they 
            were listening to the singers themselves, or "craning their necks 
            to get a glimpse of the singer," or "rushing from all directions 
            to see the singer..." But in each case the source of the "beautiful 
            voices" was a "Victor." 
          Consumers were offered the consolation 
            regarding their mistakes with the explanation that "Even in the 
            Victor laboratory, employees often imagine they are listening 
            to a singer making a record while they really hear the Victor."
          And the final advice? "Why not 
            hear the Victor for yourself? Any Victor dealer will 
            gladly play any Victor Records you want to hear."
