Cover from the USA!

Today I got a cool cover from the USA! The cover was sent from the United States Post Office and Courthouse, also known as the Texarkana Post Office and Courthouse. The building is unique because it is the only post office and federal building that is located in two states. It sits on the border between the states of Texas and Arkansas, hence the name. It was built in 1933 and is located along State Line Avenue. The postmark applied on the cover shows a Texarkana, TX location.
