A vintage shirt from WACR (W Allentown College Radio) in Allentown, Pennsylvania.  WACR apparently still broadcasts (a student handbook from 2013-2014  lists them in the campus directory) but there doesn't seem to be any online presence for the station.  Allentown College changed names in 2001 to DeSales University which also has an internet-only station WDSR.  The WDSR Facebook page says that WACR began broadcasting in 1975.

WLRS

WLRS signed on the air in 1964, originally as a training ground for students at the (W) Louisville Radio School in Louisville, Kentucky.  The station was at its peak in the 1970s as an Album Oriented Rock station and topped the city's Arbitron ratings in 1978.  In 1991 they flipped to Adult Contemporary as "Mix 102" and about six years later switched to Alternative Rock.  WLRS later moved up the dial to 105.1 FM, while 102.3 became WULV with a Soft AC format.  102.3 FM is currently Hot AC "The Max" WXMA.  Airchecks, photos and other memorabilia from the glory days of "The Walrus" can be found here.

Radio at Pitt began in the late 1950s when a group of students formed the Student Broadcasting Association with the intent of getting a station on the air.  Led by Adrian Cronauer (whose wartime experiences became the basis for the 1987 movie Good Morning Vietnam) they finally succeeded in 1961 broadcasting at 820 AM with call letters WPGH.  The struggle to find room on the FM dial ended in 1984 when the FCC granted them the last ever 10-watt Class D license to a station on the commercial band.

KCLB

Yesterday I posted a bunch of stickers from KRXQ "93 Rock" in Sacramento, California.  The above decal was filed in with them but it's pretty clear that this sticker isn't from KRXQ.  It's probably from 93.7 KCLB which was known as "The Rock" from 1991 until 2005.  KCLB is licensed to Coachella, CA...nowhere near Sacramento.
