The TBD Ishihara Shirt is inspired by color blind tests crated by Shinobu Ishihara in Tokyo, Japan.  The tests were created in 1918 after studying ophthalmology at the University of Tokyo beginning in 1908.  These tests were made to test ones ability to differentiate colors. Shinobu would test them on his color blind assistant through the trials of creating them.  Our TBD Ishihara Shirt is a color blind test on the front with the letters "TBD" visible to those that are not color blind. The back of the shirt is left blank.

This shirt is 100% Cotton. The tags of the shirt are stitched in and have a hand written size.  Please machine wash cold and air dry.
