This was the picture board I made for my Mom's surprise 80th birthday party. It came out great!! I used one piece of foam core board for each number ($1 at Dollar Tree) as the backing, printed pictures in a Word document grayscale (maybe cheaper to have printed at office supply), and glued (glue stick) and taped (invisible) the pictures on the front and back. Making the stands was more of a challenge. Enjoyed by all!!
