When it’s not what as it seems, if the artworks got damaged, then who will take responsibilities?
Oftenly, this kind of mistake occurs in the process of artwork delivery: Scratches, damage, cracks, chipping, stains, or else. The question is when did it happen? Who caused the damage? And whom should be responsible for it? That’s why you always need to do a Condition Report before or after receiving the artwork. This is something that professional should always pay attention to.
