The Autism Puzzle became a universal sign for autism awareness in 1999. Its puzzle pattern reflects the complexity of the autism spectrum. The different colors and shapes represent the diversity of the people and families living with the condition. Our Autism Puzzle Pin is die struck from jeweler's metal and plated in silver. This pin includes a clutch back and is individually poly bagged. Hand out at a fundraiser or wear them on your purse strap and coat lapel.
