Gas or electricity?

  The idea of a pipeline supplying gas to houses for heat, cooking and light was revolutionary in the late 19th century but by the turn of the century, electricity was becoming practical enough to threaten the gases dominance. This somewhat awkward cartoon tries to illustrate that point.

 I've rented apartments that still had the capped-off gas pipe that used to be the light for the room. They generally still had the 80 plus year old flowery wallpaper. Oh, they also generally had one outlet in the room because who could need more than an electric clock or bedside light in a bedroom?
