Sometimes, you need a Batman shirt to remind you that when the going gets tough, the tough cry "Uncle" and put out the bat signal. This Batman Keep Calm and Call Batman Men's Black tee does just that, a fun play on the classic, "Keep Calm and Carry On" propaganda posters from WW2. Made from comfy 100% cotton, this Batman t-shirt features a bold yellow screen print of the Batman logo and block lettering.
