You'll receive this unique background for Windows/Mac/Linux computers and laptops in three different ... sizes: * 1920 x 1080 px * 2560 x 1600 px * 3840 x 2160 px If you should need the background in a resolution not available please just let me know, and it'll be created as a free extra. Those are all PNGs. This is a custom design which has been sold to very few persons - to be exact, I've sold one T-Shirt so far :) You can find it on Amazon or Spreadshirt from time to time. Until now, there are three variants of the Bitcoin Monkey King design out in the wild. This is the third one, and I merely named it Gamma because of this fact. The Bitcoin Monkey King design stays my intellectual property, and the copyright is not available unless someone manages to convince me of the contrary.
