Slow Down!!! T-Shirt
Everyone in astronomy knows that the Doppler Effect causes visible objects to shift toward the blue spectrum when they are moving very quickly toward you. So this shirt can serve as an excellent warning to astronomy majors that they are walking too fast! If the planet on the shirt appears to be blue, they must be traveling at an incredible speed, and should probably slow down before they burn up from friction with molecules in the atmosphere.

Have had Zazzle complete a number of T-shirt projects in the past. This one had several design elements. It was well done. I will work with Zazzle again.

The T shirt seems to be made from decent material but appears to be an irregular t-shirt sewn and stitched. .

I ordered about 20 shirts for a reunion. They arrived today on time but one the package was damaged. The shirts look great but the packaging was busted open and had been taped up. The shirts that were in the torn side were really dirty and I’m not sure it will wash out as it looks like greasy dirt. The printing looked great.
