These shirts have been printed many times, many different ways.  The first several batches were printed on my kitchen table without any registration in 2006.  I designed the bird and eggs so that they could fit on the branch and nest with a pretty big margin of error but still look good.  There were also several limited editions of posters using the same art and printing method, just with different papers and colors.  This shirt was later printed by a print shop (other than my kitchen) for tours during 2007.
