Illinois state flags available at United States Flag Store range in size from 4" x 6" to 6' x 10' and come in either Superknit polyester or top-quality nylon. The nylon flags are reinforced with a strong canvas heading and a pair of brass grommets. Lapel pins and embroidered patches with a replica of the Illinois flag are also available. The Illinois flag depicts the Great Seal of Illinois against a white background. The state's name was added to the flag in 1969 to ensure that people not familiar with the Great Seal of Illinois would still recognize the banner. Order from United States Flag Store and your flag can be expected to ship within 3-5 business days.
