Forum:"Mihawk sought out Shanks"?

I've seen this in both Mihawks and Shanks articles but never seen it being mentioned in the manga. Does anyone know where this came from?

Edit: I apologize for not being a bit more clear. In Shanks' article, under Mihawk in the relationship section, it states that "Mihawk sought out Shanks on many occasion to duel". The same thing is said in Mihawk's article in the second paragraph of the History section. I've searched and haven't seen resource for this being said, but have seen a lot of people saying it for some reason. It doesn't appear to be from the manga, SBS, or even from a databook, so I am wondering if anyone knew what brought it about.98.66.209.75

You need to be more specific about when this happened. 06:58, October 28, 2013 (UTC)
