Wardour-street (n.)
"affected pseudo-archaic diction of historical novels," 1888, from street in London lined with shops selling imitation-antique furniture.
This is not literary English of any date; this is Wardour-Street Early English -- a perfectly modern article with a sham appearance of the real antique about it. [A. Ballantyne, "Wardour-Street English," Longman's Magazine, October, 1888]
