KRKY

1550 AM KRKY used to be on the air in Winfield, Kansas.  That's about all I know.  Various Broadcasting Yearbooks from the 1970s through the 2000s list AM 1550 as having multiple other call letters (KNIC, KVFW, KKLE) but I haven't been able to pinpoint when KRKY existed or their format.  If you happen to know, leave a comment.  I don't really feel like looking through every Yearbook trying to find out.  There's a coupon for Ken's Pizza on the back if that helps any Winfieldians who happen to read this--no expiration date unfortunately.
 

KNFO

KNFO existed in Waco, Texas from 1980 until 1993, many of those years as a Country station.  I'm not sure what's going on with the shape of the state of Texas shown on this sticker.  It appears a little fat in the east like they annexed parts of Oklahoma, Arkansas and Louisiana.
