The term 'art deco' was formally coined in 1925, but the roots of the movement go back to the turn of the century. Or at least that's what five minutes of internet research tells me.
So Luger couldn't have been deliberately emulating the not-yet-established Art Deco style. However, it's set in the same zeitgeist that would give rise to Art Deco, and since it was at least in part designed for elegant aesthetics, it could kinda-sorta-maybe but-not-really be called Art Deco?
