Although Michelangelo's David is pushing out of the very edge of the classical period, this image is too weird to ignore!  I found this image on a website showing how the immediate recognition of classical art is useful for effective advertising. 

"The great thing about using classical art in advertising is its familiarity to viewers. The incongruity resulting from the addition of advertising elements only adds to the visual appeal. In other words, it gets noticed. Another plus—the artwork is usually copyright free" (blog.selsiusrealestate.com)
