WABE

90.1 FM WABE is a public radio station and NPR affiliate in Atlanta, Georgia.  They are owned by the city's public school system which explains the call letter meaning--(W) Atlanta Board of Education.  These giant 15-inch long stickers date to when they primarily aired Classical music which is now relegated to weekends.  WABE has been on the air since 1948 and were probably the first-ever non-commercial station in the southern US, at least on the FM band.
