Made from sustianbly sourced 4mm Plywood with added plywood circles on the back to ensure seure fitting of the D-ring hooks to hang it with. (Picture of the back is in the gallery) It has Japanese cream thread on the back ready so you can hang your plaque up straightaway. We decided to use the 4mm plywood to keep the weight of it down - this means it will happlily hang on a little panel pin. No need for big nails or screws in the wall.
