" many of the posters need
to be re-lilnenbacked and restored as the original linenbacking job was very
poor, many just linenbacked and no restoration at all (pin holes still in corners, small holes still in
poster. )"
I don't know if I would call this minimalist approach to backing as being poor, in fact many people are starting to prefer that no restoration be done to their posters if not necessary. But as much disclosure as possible is always good and thanks for the update.
