This was machined from 3/8" aluminum with the "wings" stepped down progressively. I engraved the sparrow and the text and applied copper leaf to go with the campers brass and copper theme. I then polished and clearcoated it. I saw an emblem like this but three feet tall at a flea market. It boldly stated " Golden Eagle". It would not fit on my camper and I can't afford gold, so we are "The Brass Sparrow" !!!
