Humanoids has announced it bought the company's long-missing original logo, hand-drawn in 1974 by co-founder Jean “Moebius” Giraud.

The inked piece, measuring 4.25 inches by 6 inches, was purchased Friday for $6,572.50 in the same Heritage Auctions sale that featured the earliest Superman cover art known to exist.

Moebius teamed with Jean-Pierre Dionnet, Philippe Druillet and Bernard Farkas in December 1974 to form the Paris art collective Les Humanoïdes Associés in order to publish Métal Hurlant, the revolutionary sci-fi anthology that spawned several foreign versions, including the U.S. magazine Heavy Metal.

Now called simply Humanoids, the graphic novel publisher relocated it headquarters last year to Los Angeles and opened an office in Tokyo.

Moebius, the enormously influential artist whose works included The Airtight Garage, The Incal and Blueberry, died in May 2012 at age 73.
