Arkitip
Jon’s work has been featured in several issues of Arkitip. Though I can’t place the exact issue in which this doodled envelope was found, it fits perfectly with the magazine’s commitment to site-specific artwork: Arkitip delivers original, site specific artwork in every issue. The assignment for the artists who contribute is to create something original to run in the magazine. Artists have the opportunity to design and layout the art they contribute as well. Making a contribution to Arkitip is like creating your own “installation” that is then distributed around the world. It’s like a traveling exhibition that you can take home.
[UPDATE 1/2/09: Thanks to the comment below from Ian, we think this image appears in Arkitip issue 26 which is long gone, but a few appear to still be available for $100 directly from Arkitip here.]
