We have a new collection at The Tee Party, we hope, the first of many collections. This first one, "IM-POSS-IBLE" pays homage to the classic optical illusion shapes pioneered by Oscar Reutersvärd in the 1930's and made famous in popular culture by their inclusion in graphic artworks by M. C. Escher.

The Impossible Triangle, described by Roger Penrose as "impossibility in it's purist form" is the first of the shapes, followed by Impossible Square and Impossibe Pentagon.



These simple shapes make for impossibly cool t-shirt designs.
