Of the over 30 years I have been in framing, it amazes me how framers treat, mount and frame art and artifacts for people who patronize them. On a weekly basis, it's not unusual for someone to contact me through email or phone informing me of a recently framed item which shows signs of deterioration.
When a photograph, document or other item has fading, it is nearly impossible to restore it to its original condition. And, do you notice those stores that offer photo restoration? Well, they aren't really restoring the photo.
