[QUOTE="Pat P, post: 584711, member: 201"]Have you looked at it under a loupe? The things I'd look for are if there are any kind of dots in the areas where there's color and text, whether you can see any foxing (brown discoloration), and what kind of paper it is. If it's older, laid paper, you would see horizontal and vertical darker areas in the paper but without light behind it, it can be hard to see it. Paper from before the early to mid-1800s can look surprisingly fresh and clean since it was cotton-based. Later paper was usually based on wood pulp, which introduced acid and caused the aging we're used to thinking old paper should look like. I had a set of botanical bookplates that I knew were from the 1700s and the paper was still rather white.[/QUOTE]
