Barry is correct in that one should be very cautious when comparing scanned images. Examination of and comparison to original images should, if possible, be the preferred approach. I also agree with Scott's point that one could find a genuine Williamson mount and replace its photo with a fake.

I'd be very interested to compare the resolution (as opposed to the contrast) of this image to the one at the LOC. Even the slightest difference would suggest to me that it is a fake. Same too for the lettering on the mount. Differences in resolution can be very subtle and such a comparison should be made by comparing originals.

As has been discussed in this thread, there is a lot that can be done to assuage concerns that the CdV is not authentic, and I would respectfully urge the auction house to do it.
