These are a selection of poster advertisements done by various papers to attract readers:
The Times, going with 'A short sharp read' combining it with ballet, to show that no matter what you need to be connected with the news, and just how quick it is to read and yet intake so much.
The Financial Times, in these two posters go with 'some tools aren't a luxury' as a heading. This is combined with the lacking of the parachute and lack of guns as the 'tools'. So it fits with the papers name, the financial side of things.
The Shropshire Star wanted to promote their sponsorship of the annual RAF Cosford Air Show. Therefore making their newspaper a paper airoplane was the idea they eventually came up with.
