Rimmel Mandarin Red

Is this the oldest existing lipstick still in use? I remember this from when we lived in London, and that was the end of the 70s. It might even be a 60s original.

Although not used day to day, it still gets wheeled out for the odd fancy dress do. My sister was the last to give it a night out, this Halloween, and although she said it made her lips itch, she suffered no after effects.
