Clay Matthews Green Bay Packers Plastic Sign. Measures 11x17 and is made of VERY DURABLE styrene. A great substitute for a poster because it can be washed with soap and water and is nearly indestructible. Has a die cut hole in the top for hanging. Looks great in your Man Cave, bedroom wall or even in your garage! Please check out my other Green Bay Packers items for sale. Also available at The C-Town Sports Cave in Mentor, Ohio inside The Great Lakes Mall.
