The Montblanc Jules Verne was only available as a fountain pen and ballpoint; a rollerball never existed. The model was furthermore only delivered in blue, since other colours would not have made thematic sense (reference to the sea); the original also has a larger diameter than the counterfeits. The pieces shown in the auction in question are clearly to be classified as counterfeits; the etui can be recognised as forged by its too-short flap. With the Bohème, authenticity is harder to assess from the pictures, but the included etui is also a fake.
