I'm a bit confused as to what the source of it is, as far as I can remember I don't remember Law using observation haki at all in the series (although maybe I'm mistaken) and his profile makes no mention of the source of it being included on his profile. I checked the One Piece wiki and they have it listed there as well, their source is his Vivre card... Except, I went through the Vivre card's and law's makes no mention of him having observation haki.
