Sizing and Washing Tips
This is your visual system slipping on a banana peel. Be sure to check out the detail shot on the product page. In this motion illusion, the implied shadowing is not consistent with a single light source, causing dissonance in your personal wetware visual subsystem. Spurious motion is added when it tries to reconcile the implied shadowing of neighboring objects as your eyes wander over this confused state of affairs (hey, wait, we are not making any reference here to the state of politics in California or anywhere else, really, we're not).

In addition to the rolling motion effect, which people see to varying degrees, there is also a more subtle illusion: very fine and fleeting grid lines seem to appear between the pattern of "stamps" as you move your gaze over the full size image. These lines are another tiny clue via brain bugs as to what the visual cortex is up to. Obviously further tee-shirt-based science is called for in the area of illusions.

Thanks to the Libre Map Project for making wonderful SVG outlines of the great state of California, and all the other great states, available online.

The men's relaxed fit t-shirts run small, so please order one size larger than your usual. The other styles run true to size. We wish we could bring you samples, but we’re waiting for improvements to current teleportation technology.
  • The men's relaxed fit tee is a heavier cotton with a looser fit. They run small, so order one size larger than usual.
  • The men's trim fit tee is more fitted and a medium weight ring spun cotton. We print up to 4XL in this style!
  • The women's v-neck is a medium ring spun cotton with short sleeves.
  • Youth shirts are suitable for both boys and girls in a heavy ring spun cotton .
  • We recommend machine washing in cold water with the shirt inside out; tumble dry on low or medium. If you iron (wow!), we recommend turning the shirt inside out first.
