CC0_Practice_1801 is a response to Taiwanese artist Pinhua Chen’s project Time Travel, which is an ongoing exhibition where he dedicates his work to the public domain by waiving all rights to the works worldwide under copyright law. This is practiced under a copyright option defined by Creative Commons Zero (CC0). By declaring that there are “no rights reserved”, anyone is allowed and encouraged to copy, modify, distribute, and perform his work, even for commercial purposes, all without asking permission.

Below is a collection of four posters designed with two of the hundreds of images that he has already dedicated to the public. In order to preserve and extend the spirit of his project, I have released all four images to the internet, each in PDF and TIFF formats. The TIFF files are unflattened and include all the original layers for potential modification. Free downloads can be found here:
