Wow! Now that’s impressive. Great detective work.

Where have you been all my life?

(At least for the past year, that is)

Dude:
That was while I killing time waiting for a conference call. If I had the time to devote to this, I could raster those images several different ways and improve shading to get the real images, zap the current letters and give the eye a better view and let the brain work on them, negatives, reverse, shading, etc. All the same stuff I have you do.

That short form BC is bullshit. It is so marked up it isn't funny. And yet, it appears to have newer typing placed on it, in a couple of areas. With inconsistent fonts 3 times.

Any kid with freeware could do this and prove it is altered and fake.

In terms of the cross hatching, this doc was produced in 1980 and I think I have seen it before. So it may have been sold as security feature.

Clearly, someone has altered these docs. violate the integrity of the document.

Think of it as a wax seal on a closed door. The wax may be re poured by some professional but you can tell someone altered the seal and something inside is missing.
