Sydsvenskan in Sweden are well known for doing crazy advertising billboards, however not all of them last...
I was talking a walk in our lovely fall rain when I spotted a giant diary on the street. Actually, it was an advertising poster that looked like a diary. 'Open me' it beckoned, so open it I did....."
Inside the poster headline said something like "curious? read the personal pages of Sydsvenskan.." or similar, I can't remember because as I was opening the diary door - ker-unch! - the door fell of the billboard.
It was really quite easy to see why, the cover was heavy and the only thing keeping it up was double sided tape. Yup, a heavy wood and paper cover was only stuck with double sided tape. And they expected people to mess with it like I did.
So, dear Sydsvenskan, I'll give you eight points for your curiosity killed the cat idea, but a mediocre 2 for the physical execution. But don't let this minor setback stop you from doing crazy posters in the future, just try again!
