Edison became concerned with America's reliance on foreign supply of rubber and was determined to find a native supply of rubber. Edison's work on rubber took place largely at his research laboratory in Fort Myers, which has been designated as a National Historic Chemical Landmark. The laboratory was built after Thomas Edison, Henry Ford, and Harvey Firestone pulled together $75,000 to form the Edison Botanical Research Corporation. Dimensions: 15.75"W x 22"H
