Kanizsa triangle optical illusion T-Shirt
The Kanizsa triangle is an optical illusion first discovered by the Italian psychologist Gaetano Kanizsa in 1955. In the design a solid colour equilateral triangle is perceived, but in fact, none is drawn. This effect is known as a subjective or "illusory contour." Also, the nonexistent solid colour triangle appears to be brighter than the surrounding area, but in fact, it has the same brightness as the background.
It looks good on a T-shirt, too!

I purchased this to test to see if zazzle was producing good quality.
Needless to say, they are.
The sizing runs a bit on the small size though. Print quality is perfect. What you see on the screen is what you get.

Ordered the Irish terrier t shirt. I love it! There was a slight issue with sizing ( my fault) but their customer service was amazing. New t shirt within 5 days. I recommend getting 1 to 2 sizes bigger. I am wearing Men's size large.
