Egg chair, fake or..  

(to be clear)

Looks fake to me
Unless the photo is distorted, the curves of the chair look close but not right for Fritz Hansen production.
If the seller tells you it's Italian production, why would you think its anything other than fake? Most times dubious sellers are being vague in hopes that you will think it's real. Sounds like this seller is being honest about it being a knock-off.
