Folder: S.F. Streets-Potrero Avenue.
Newscopy: "WAITING--The traffic signals at 25th-st and Potrero-av are blocked from drivers' view when they're working - but more often than not, they aren't working - and children from the Starr King School and the Good Samaritan Center nearby must take their lives in their hands crossing through heavy traffic when no policeman is on duty. Here, under a blank signal, Mrs. Margaret Bell, play school-teacher, waits with pupils for a chance to dodge across the street.".
