I was similarly baffled years ago by signs around San Juan, Puerto Rico that seemed to be gibberish (Spanish gibberish, like mangled words) and then a few weeks later, with phone numbers added to them. Turned out to be a creative Herbalife campaign. I think this sort of plastering signs all around is illegal now, I haven't seen it in years, but it was common in many places I visited a number of years ago. And then there is Adelaide, AU where there are dozens of blue and white signs on buildings saying 'POLITES'. It seems something official at first, until you notice how many there are. Turns out these are all buildings owned by a single guy of (IIRC) Greek decent who just likes to show his accomplishments as a real estate mogul by putting his name on all buildings he owns. Sometimes it's a weird world we live in.
