I came across this logo for a company called Claimair. It has been really cleverly designed. The icon is obviously a paper aeroplane. The thing that makes its clever is the fact that this company specialises in helping people with the paperwork when making a complaint against an airline.
This is what design is all about. It is about thinking outside the box. Some people may look at this and think that its quite obvious, but guaranteed, most people would have just created something really boring using the name of the company and stretching possibly t incorporating something vaguely to do with and aeroplane. Although this is very literal, it is also one of the best concepts for a logo that I have seen. Really brilliant!
