It's the sign that's been trolling air passengers for 27 years -- 'Welcome to Cleveland,' just as you're about to land at Mitchell International Airport... In Milwaukee.
One afternoon in 1978, artist and photographer, Mark Gubin, was having lunch on his roof with a colleague when he realised that he was sitting was under a flight path.
His colleague commented that it'd be nice to have a 'Welcome to Milwaukee' sign up there. But Gubin had a far better idea...
In 2005, Gubin told Journal Sentinel: "There's not a real purpose for having this here except madness, which I tend to be pretty good at.
"It was all tongue-in-cheek, just for fun. Living in the real world is not a dress rehearsal. You better have fun with it."
