Pallet Frames

For my sons airplane/helicopter Birthday I painted murals on 2inch thick cardboard. three mnths later they are still in the back yard, the cardboard has been rained on as well as the sprinklers have watered them almost daily and as you see they're still intact. so i decided to build them a frame out of pallet boards and hang them on the wall in the backyard. Since I used pallet boards, nails i already had, and remaining spray paint I have from my tractor tire project. This project cost me practically nothing, had to by anchor screws to hang..
