In 2003, the Fort Worth Astronomical Society held a contest among its members to update it's older "arch" logo (upper left) to something newer and dynamic which represented the long-time association with the city of Fort Worth, and better represented our hobby with a more prominant telescope, and the single star in the base representing the Lone Star State of Texas. The evolution of the logo is shown to the right.
The "diamond" style (upper right) was the winning design. This was subsequently modified to a round shield style with slight modifications to the panther over the next few years.
FWAS adopted the current logo depicting the sleeping panther atop its shield in reference to its historical association with the city of Fort Worth (i.e. "Panther City"). Over the last few years the logo has been changed to have a round shield, and the panther itself has been modified a couple of times, but the basic design has remained unchanged.
