how do i upload picture onto my post if its not on the internet?

Thanks for the info guys! Yes the are Artbox cards but i dont have pictures. I have just asked the seller to send me some.

Unless they are selling them for a couple hundred dollars they are likely fake due to the rarity and the small amount of real ones existing. The odds on pulling a signed Harry Potter card from a pack is 48/1. If you opened 48 packs you might get an autograph card.

Here is a good blog that caught some of the many counterfeits out there.

HI all. I'mm thinking of purchasing some harry potter autograph cards. I just wanted to make sure that before I buy them they are authentic. I know that it says that they are personally signed on the back but I just wanted to make sure.
Thanks!
