The ID slide above is part of Canadian television history. When CBLT, the local TORONTO channel went on the air for the first time, viewers were greeted by a back-to-front, upside down slide, put there by an overly-fastidious technician.
EMIL ZVARICH got his 15 minutes of fame by cleaning the slide one last time, and then popping it into the projector and up it went to air. Making things worse, all the CBC brass were in the control room at the time. Then a film jammed in the projector gate. It was September 8, 1952 – and CBLT was born.
