How could I identify my wassily chair as a genuine wassily chair? I would like to try to avoid taking it to antique shops and auctioneers, as they are hard to get in touch with for such things (especially if they know that they will not be able to get it from you to sell for themselves). Maybe there is some way I can see some key identifiers for myself, such as if there are some “dead giveaways” that this is in fact a genuine wassily chair? Perhaps someone reading this has already encountered this and will have some advice. Until then, thanks a lot!
