Beautifully engraved certificate from the Dunlop Rubber Company issued in 1964. This historic document has an ornate border around it. This item is hand signed by the Company's Director and Secretary and is over 38 years old. John Dunlop, a veterinarian in Belfast, Ireland was the first person to try his hand at the rubber tire. In 1888, Dunlop attempted to make air filled tires for his son's bicycle. He used a thin rubber sheet covered with fabric. When the tires appeared to be a success, he applied for a patent for pneumatic bicycle tires. In 1889, Dunlop sold his tire idea to Harvey du Cross, Jr., who started the Dunlop Rubber Company.
