Although not a "bill-board", 707-458 ex 4X-ATB sat outside Tegel Airport in Berlin painted as Lufthansa D-ABOC (I first saw it in 1994). It was famous for its involvement in an infamous hijack in 1970.
The 707 mentioned by gruntie and tail wheel (ex VH-EBP) as "The Plane" café at Cairo was also SU-BBA. I saw it there in June 1995.
