I'm a former picture framer too and in my career I used acid free materials
so I know the value of them. I think it's all relative as magazines and
newspapers are not acid free either. I suppose that in making work to sell
then we should reproduce the images onto acid free paper rather than use the
original? This makes sense for fine art work. There is also a concern for
artists that do assemblage as wood is even more acidic than paper. Maybe with
proper sealing it wouldn't be an issue.
