Retro Flavored Pi Baseball T-Shirt

by jswhittington3
$26
Description

Parody of John 3.16 shirt designs. Instead of stating John 3:16, it shows John 3.14 going on toward the rest of the numbers of Pi. Simple idea, but elegant and funny all at once. Great nerd humor design. Idea and design were created on Leap Day, 2016.
