I’m not sure when we started noticing these, but while we don’t have blue man crosswalk signs in the States (as far as I know), it quickly became clear that everywhere else in the world does have them.
They vary greatly in their design. Finland (not surprisingly) had the most graphically polished version. Vietnam on the other hand had an almost endless variety of signs, most of which looked like they were hand done; practically no two were the same. Assembled below is a collection of the ones we’ve shot so far.
