Today, feeling nostalgic, I opened up my secret briefcase full of childhood trading cards to find some of my cards had cupped rather severely. Warping isn't that big of a deal with trading cards. Pressure and time will flatten them properly, but it got me worrying about my posters. I keep my posters in mylar sleeves in the same room, almost identically to my cards, so I had to take a look. On one or two of my posters, there is some
very light rippling along the bottom edge.
I was justly mortified. I plugged in my dehumidifier and placed it next to my collection.
This drew my attention to the poster I have framed. I had noticed some light waves before, but I blamed it on the frame, and I was never too concerned. I also have this poster "archived" in my collection, so I don't particularly care if it got ruined. I decided to take a picture of it, because I'm planning on framing several more pieces and want to arrange them pleasingly. The first picture came out fine.
Then I took a picture from a distance.
To my horror, the camera flash revealed the waves in my poster to be far more pronounced than I had originally believed. I'm beginning to fear the environment I live in is not suitable for my posters, many of which were expensive and difficult for me to acquire, and I'm panicking. I don't much care about the one in the frame, but the extremely minor waves on two or three of my precious posters are extremely concerning. Is there any way to remedy this damage?
With my collection becoming more ambitious, I can't in the right mind continue collecting until I know my posters can be safe. Is this due to humidity? Can I flatten out the waves just like my trading cards? Is this moisture still trapped in the paper at this very moment?
This is a nightmare for me. HELP.
