<p>A picture such as a photographic print is formed to a concave/convex configuration for aesthetic reasons by fixing the flat print to a flat sheet metal mount with an interposed adhesive, the sheet metal having a central hole, and the assembly then being press formed to provide the curvature. The central hole avoids an unsatisfactory result due to the formation of air bubbles in the adhesive.</p> |
