Of the Greta Garbo there officially existed three variants as fountain pen and ballpoint, however never a rollerball and no version with black upper part. A version offered as Greta Garbo rollerball with black upper part is therefore most likely a counterfeit. Even the detail of the pearl on the clip looks on such pieces often poorly attached, which confirms the suspicion. In case of doubt the writing instrument should be presented to a specialist retailer.
