Things You'll Need
Books, cans or other weights
Self-adhesive photo corners
Mounting a poster on foam board not only gives it a stable backing but also makes display and framing much easier. While you could use regular craft glue, there's a high risk of damaging the poster and leaving wrinkles and ridges. Other options will leave your poster pristine and make for an attractive display.

Quick and Simple Attachments
Place the foam board on a flat surface.
Center the poster on the foam-core sheet.
Place books, soup cans or other heavy objects on the poster to hold it in place.
Lift a corner of the poster and place a 2-inch strip of double-sided transparent tape on the foam board, directly under the corner of the poster.
Peel the protective backing from the tape and press the poster corner onto it.
Move across the top of the poster, about a quarter of the width, and place another piece of tape. Repeat about halfway and about three-quarters of the way across, as well as in the next corner.
Repeat the tape placement along each side and the bottom of the poster.
Remove the weights.
Securely Removable Solutions
Set the foam board flat on your work surface.
Slide the corners of the poster into self-adhesive photo corners.
Position the poster on the foam board.
Remove the backing from the adhesive side of the photo corners and press them onto the board.
Spray Away to Adhere It
Lay the foam board on a flat surface.
Place the poster on the board with the back side facing up.
Spray the back of the poster lightly with an acid-free spray adhesive.
Turn the poster over carefully and position it on the board.
Smooth the poster from the center to the edges, using either the side of your hand or a ruler.
Clamping the edges of the poster to the board can help make the spray adhesive more permanent.
Be sure to use acid-free paper and adhesives to preserve the integrity of your poster as time goes by.
