The first Greta Garbo counterfeits reach Germany and are visually so good that recognition is difficult. A central indication, however, is the model itself: no official Greta Garbo rollerball exists; an offered rollerball must therefore necessarily be a counterfeit. The same sellers often also offer other known plagiarisms, e.g. StarWalker Rubber fakes, which likewise serves as a warning signal. Collectors notify on suspicion directly the highest bidders and eBay.
