The idea behind t-shirt of the week (more often month) is a bit like the old section in Wired magazine called Japanese Schoolgirl Watch. This might sound a little iffy, but is actually about trends and, in particular, catching a shift early. (In Japan, School Girls were often onto fashion trends way before anyone else). It’s much the same with bumper stickers and especially t-shirts. They can express a sentiment, micro-trend or weak signal that perhaps isn’t so obvious elsewhere. Normally my t-shirt posts have a social or political angle. This one just made me laugh.
