Rare1982 Black & White Wichita River Festival Button

Description

There were two different Riverfest buttons issued in 1982.  The most common version is the one with the tan circle and light blue omega near the perimeter of the button.
The rarer
button is referred to as the pure black & white version which does not have the tan circle or light blue omega.  The second picture shows a comparison of the two buttons. Only the pure black & white is a part of this auction. No one seems to know how many of the B&Ws were released but they are definitely hard to find. The button is in very good condition as shown by the pictures. Shipping is free.
