If you have a great piece of artwork or a family photo you treasure, consider having it custom framed. Over the years it will stand the test of time. Custom framing has archival products to keep your image from turning yellow. We use UV glass to keep it from fading.
I often reframe items where it’s on cardboard and taped down. All of those items age the image. It may cost a little more than something you pick up at a big box store, but it will make all the difference in the years to come.
