How do you tell if a Ghost chair is real?

To tell if a Ghost chair is real, turn it over and examine the underside of the polycarbonate seat. A genuine piece will feature the Kartell name embossed on its surface. If the name appears on a paper label or tag, your chair may be a replica. Also, any errors in spelling or discrepancies in the font are usually signs of a counterfeit. Because there are convincing reproductions on the market, you may wish to seek the opinion of a certified appraiser or knowledgeable antique dealer when authenticating your chair.
