No Bull t-shirt. This shirt is printed on both sides. The front shows the official No Bull and the back shows the truth behind the Theory of Evolution.
This chart shows that mankind started as a small Ape, evolved through the years and developed into a cowboy (labeled as Man At His Peak), and then deteriorated when some of mankind became City Dwellers.
And that's No Bull!
This shirt is 100% pre-shrunk white cotton, size XX-Large.
