Of course, the Hornets now play in New Orleans.  I don't know if the Bobcats play in this arena or somewhere else.  It's not that old; the postcard says it was completed in 1988 and is one of the largest facilities of its kind.  

Another interesting fact from the card: Charlotte was first referred to as a "Hornet's Nest" of rebellion by General Cornwallis during the Revolutionary War.
