So cute! Find a medal piece like this and create a sign by finding plain wood that is made to be a sign from a craft store like Joan's. Paint any color all over the board and create "fake" cracks by drawing cricked lines occasionally. Then paint what you would like on the sign (picture, word, etc.) and to give it a vintage feel sand the board before painting.
made of a board pulled from a pallet, spray painted black, then painted with a brush in Valspar Antique White Eggshell, two coats. While the sign was drying I printed the letters in Times New Roman (just the outlines to save ink) and cut them out, traced on to the board, and then painted with black acrylic paint the letters. After that dried, I simply took a power sander to the sign.
