Just wondering about a couple here. I bought this off of a guy I trust, and I'm nearly certain that the signatures are authentic, the piece is numbered out of 980 like many and includes a photo of their signing. My question is that 2 of the 20 signatures look like they were gone over in a different marker and I was just wondering if that could maybe be a marker dying or some moron trying to touch up signatures he thought could use it or what. Or maybe it was just that the marker bled weird and I'm looking at it wrong. Just looking for thoughts on  reasons why it would look like that.

Thanks!
