ABSTRACT:
A bendable and shipable bulletin board comprising front and rear layers heat sealed to one another, a foam core between the front and rear layers, and at least one stiffening layer between the front and rear layers. Advantageously the front layer is sueded so pin holes will not show and the foam and stiffening layers, possibly integral, can be folded over for shipping but, upon release, will resume their flat condition.
