Eero Saarinen Tulip table - please help identify  

Hello there,
I just purchased a 91cm tulip table from a flea market in Paris. The owner said the he's working with a hotel in Cannes so that he could collect their furnitures from time to time. I'd like to know if it's genuine from knoll because there's sticker, not engraved or signed anywhere.
The table measured 91cm round, I tried with a magnet on the base and it's not sticking to it. For more details please refer to the pics I uploaded or I'll take more pics.
Thank you all very much in advance!
