Yes. They are all pirate themed.

Rationale (boring thinking-behind-the-piece bit)
To me, the more enjoyable a poster – whether that is due to a narrative element, skilful graphics or clever poster concept – the more effective it is. The very idea of the recession is so commonly (and understandably) centred on money, business and general unhappiness; none of which are particularly uplifting. So with seemingly tenuous links, I infused the recession-influenced posters with pirates; fun and adventurous and spontaneous!
Foregoing what could have possibly been an arguably more poignant and serious angle with Somalian pirates or focussing on information piracy, I chose to keep it light-hearted as that type of recession poster seems rare and challenging: speaking about such a topic in such a manner without being inappropriate. Not to mention, doom and gloom is not the best hook for people (particularly not young people).
None of the posters directly reference the recession as I don't think using buzz words (which "recession" has become) is very effective. And each poster has very few words to allow the viewer to concentrate on the image and grasp a big idea in one concise sentence.
