Cover & Postcards from the USA!

Today I got a nice cover with some postcards from the USA! The postcards show an illustrated map of the state of Oklahoma and views of Oklahoma City. Oklahoma, which is located in the South Central part of the country, was the 46th state to enter the union. It is currently the 28th most populous state and its capital is Oklahoma City. More than two thirds of its population lives in the areas of Oklahoma City and Tulsa. It is known for its vibrant economy and severe weather. Thanks Benita!
