So -ponder that for a nano second and then wonder what could Eric Clapton do to try to identify it by visual marks and markings on the instrument today ?
The picture on the cover of this Guitarist edition has enough resolution to see the grain pattern of the top. That should be enough to identify the guitar once it will come up. EC probably has the funds to buy a print of that pic in an even better resolution and that would be a forensic proof that it is the guitar.
You have to keep in mind that we never saw that iconic picture even close to it's original resolution. We only saw the version made for a low-res print for a record sleeve. The photo was taken by a professional photographer with at least a 24x36 camera but most likely even something like a middle format Hasselblad. Those cameras and lenses had a resolution that only recently were surpassed by digital cameras.
So expect the real photo in -say - a 80cm x 80cm printout to show as much details as CDaughtrys pics of his own collection.
