All the Time in the World T-Shirt

This family-friendly unisex design, depicting the geologic time scale, appeals to the scientist in everyone and for that special geo-nerd in your life. This design came about because I saw one that was similar, but much more simplified and the text sizing and colouring were inaccurate; as a geologist, I had to rectify that. The colours are an exact match to those specified by the International Chronostratigraphic Chart (http://www.stratigraphy.org/ICSchart/ChronostratChart2014-02.jpg), and the text is proportional in size to the time periods' duration relative to each other during Earth's history. The back of the shirt (as shown) includes from 4.6 billion years ago to 541 million years ago, and the front of the shirt include from 541 million years ago to present day.
