Love Pi day?  This shirt is a fun twist on a blast from the past. We combined the classic, timeless style of a certain Private Investigator, (with a fabulous mustache), and the symbol for a number that keeps on going... forever! Whether you love math, Hawaiian themed shirts or both... this one is a must have! Proudly cut & sewn in the USA.
