WJJD/WJEZ

WJJD (W John J Davis--the station's founder) AM and WJEZ FM were co-owned stations in Chicago, Illinois.  This sticker probably dates from the late 1970s when WJJD carried a traditional Country format while WJEZ was a softer Country outlet featuring instrumentals and music from the likes of Dolly Parton, Crystal Gayle and Kenny Rogers.  1160 AM is currently Christian Talk WYLL while 104.3 FM is Classic Hits WJMK.  An excellent history of both stations can be read here.
