Excellent backing boards for a movie poster collection. These are top of the line and will keep your posters in good shape for the long haul. Perfect to go inside the mylar sheets.

I ordered 30 of these backings for my 1980s movie poster collection. I used to use corrugated backings and was worried these would not be as good due to their flexibility. However, the size reduction and improved acid-free nature of the material make this a must have for any poster collection. When put in mylar sheets with a poster, the end result is perfect. The flexible nature of the backing provides enough firmness to hold the picture up to look at while being easy to get in and out of the storage box. I highly recommend these!
