How to keep 11x14's from bending when graphing IP?

[pzero]

Looking for ways to hold and keep my 11x14's safe and from getting damaged when I graph in person. I've seen some use photo proof boxes, but is that the best way? Where do you get proof boxes from?

Ive seen people use a large piece of foam board as a base, and use painters tape to hold the picture down, which seems to work pretty well.

That would be good for one, but I need something to hold 6 11x14's.

Did a quick search and I was able to find something like this that may help.

I would use poster board with photo corners. I would be careful using any kind of tape on photos.

I've been testing painters tape on a lustre photo and it's been fine.
