Completed/Finished ~ adhered to what appears as foam style 1/4" matt board for stability ~ circular grommet back tab for hanging display.  
Acceptable good preowned condition: see multiple indoor photo views (focal point frontal Floral puzzle nice w/minimal typical displayed usage wear; individualized mounting board cuts + some sporadic scuffs-creases/tape residual on reverse).
