Thanks! It's printed digitally onto synthetic paper which has some nice qualities (like being waterproof and tearproof, and and it springs back to it's proper [flat] shape nicely after it's been in the tube during shipping).
All of the art is created digitally and printed via an HP Indigo 5600 (http://www8.hp.com/us/en/commercial-printers/indigo-presses/5600.html)
We take in what block height and color you want for your poster to be printed with and generate the data. So the idea is that you may want to commemorate an event that happened on the blockchain (e.g. maybe you want the information detailing the first Counterparty burn block, or sent a transaction to someone special, or got married [https://bitcoinmagazine.com/17066/first-blockchain-wedding-2/], or even the genesis block). We will take the block height and generate the text from the getblock API call (so it contains the merkleroot, hash, confirmations, height, time, tx hashes etc.), and then form it into the proper logo for you. As you can see from the images, the text is properly wrapped to form the logo so that you can actually read it and it makes sense (the text continues from one end of the space to another, and likewise from one line to another).
The Bitcoin poster contains the first 94 blocks worth of data if you start from the genesis block, so it's a nice little way for me to have a bit of Bitcoin history on my wall.
