Enemies of Artwork

Framers are normally aware or have an idea of the enemies of artwork as they listed in books and documents that one may have at some time read; but are we aware of their significance and how detrimental they are to artwork. When I first started framing there was enough to remember and try to master other than worry or research the said enemies as there was no one reference to make this task reasonably simple. I hope this article will help as it is my intention to explain them as simple as possible.
