I couldn't find one I liked well enough for my application so I just made it myself. These are approximately 8 inch brackets with the billboard being 72x40.5. You can mount it to the side of any building to throw up advertising or video. I also added nice little details no one will probably ever see, but I made the brackets a different type of metal with rust...and they are bolted onto the billboard frame by actual phillips bolt heads for extra realism. I hope you find this billboard useful in any metaverse or city setting.
