The San Francisco-based Creative Commons organisation is a child of the internet age, devoted to helping ordinary people understand the ins and outs of complex copyright law, and publish their own work in a way that avoids it completely.
Creative Commons has grown rapidly in recent years, and now has 30 staff and additional offices in Boston and Berlin.
One of the biggest problems facing Creative Commons has been explaining the finer details of copyright law to people with little or no understanding of the law. Online, they've used clever animations - but in the real world, it can be trickier to explain.
That's why Creative Commons decided to use photos from users of online photo-sharing site flickr.com on their Business Cards. All the photos have been uploaded with a Creative Commons licence, which means the CC team is free to use the images - the photographers have granted permission in advance. There are millions of CC-licensed images on Flickr to choose from, so it's easy to make a pack of Business Cards with a different photo on every card!
The cards sum up the whole Creative Commons concept: they look amazing, using the work of others who are happy to grant permission. When a CC staffer hands over a card, they hand over a CC-licensed work of art.
As a non-profit organisation funded by donations, Creative Commons has to keep a very careful eye on every penny it spends. Buying packs of 50 cards means few get wasted, and the huge supply of amazing CC images on Flickr ensures that every one of them looks fantastic.
