Timetable Backing Board. 4-1/4 x 10". .028" thick acid-free material. White both sides. Long-term storage.

Very satisfied with purchase

I have a collection of several hundred old railroad timetables, many of them well over a hundred years old. Some are a bit fragile with age. These acid-free backing boards, in conjunction with Bags Unlimited's 4 3/8" by 10" archival timetable sleeves (STT25), provide the perfect means of safely storing these old items. Collectors like me don't exactly "own" these things. We are, in the long run, merely caretakers of this history until they are one day passed along to someone else. It's important to do the right thing to carefully archive such things, and these folks have just the right products to do that.
