The more I look at it, the more I realize just how phenomenal the photograph is. Two people in lockstep going in one direction, two in the opposite (how metaphorically true!). One person appears to have one body and two heads, each looking in the opposite direction (split personality?... again, how metaphorical). Black and white world they are in... no shades of gray, no middle tone, just stark irreconcilable differences (did I say how metaphorical?). And the cold world of modern architecture... straight lines, sharp angles. What a beauty!
