This Super Mario Bros. t-shirt shows Mario in the Minus World. The shirt reads Original Glitch.

In Super Mario Bros., the Mushroom Kingdom was invaded by the Koopa, and Princess Toadstool was held captive by Bowser. A player took control of Mario and was tasked with sending him through various levels to save the princess. One unforeseen obstacle for Mario came in the Minus World, where the level could not be finished due to the pipe at the end being glitched and taking the player back to the start.

Even with its share of glitches, Super Mario Bros. received critical acclaim and is considered one of the best games of all time. Now, you can show that you are a fan with this Original Glitch Super Mario Bros. T-Shirt!
