1560 AM KEGG was a Country station (at least when this sticker was printed) from Daingerfield, Texas. After reading the little bit of history I could find on this station, it seems they've had quite a few formats over the years and a fair amount of poor ownership. If this bulletin board post can be believed, in 1994 they switched to Urban yet, amazingly, carried Rush Limbaugh in the afternoon. 1560 AM is currently a Country Gospel station, "King Country Radio" KNGR.
This jumbo sticker measures a whopping 15" across.
