Ive seen a lot of Bromides where the art has been touched up to remove faults and to darken areas which didn't come out right, so pen and razor marks can be seen on these production pages. Its very unlikely that it would have been sent to Cam at any point but could have been signed by Cam at any con here was at, it have been a much cooler item to get signed than the average book. It would not be the first time someone bought a Bromide as a real piece of art this kind of thing could happen to any of us.
