Valley Forge's Spectrapro™ Polyester State Flags are resiliently constructed with 100% 2x2 ply spun polyester. Their durability and strength make them ideal flags for flying on a daily basis or in extreme conditions such as high wind. Each flag is finished with a heavy canvas heading and brass grommets, and care is taken to reproduce accurately all fine detail in intricate emblems.
The Maryland state flag is the only state flag to be based on English heraldry. It is based on the Calvert family coat of arms, and was adopted in 1909. The North American Vexillological Association ranks the Maryland state flag 4th overall out of 72 U.S. States, Territories, and Canadian Provinces.
