SALT LAKE CITY — A huge 30-by-60 foot U.S. flag is displayed on the west side of the Salt Lake Plaza Hotel to welcome members of the North American Vexillological Association to Salt Lake City for its 47th annual meeting.

The association is a scholarly, nonprofit organization dedicated to the pursuit of vexillology — the scientific study of flag history and symbolism.

This is the first time the association has held its annual meeting in Salt Lake City.

The event got underway Friday and runs through Sunday.
