I had this interesting map of Electric Transport of Sao Paulo Brazil dated 1980 in my archive.  Map shows trolleybus lines, trolley bus lines under construction, metro stations at that time and the former tram network.  I hope that some of you will find this map useful.  "Trolley Coach News" is no longer published after many decades.
