any sheets underneath it. This may be more visible from the rear.

Also, the colours on the copies are unlikely to exactly match the
original, although the copies may well match each other.

I am basing it on the `copy` is more solid colour and if correct as one
poster has stated the wet ink on the original shows the fibres of the paper.

Agree, disagree?
