  • Abstract
    PRIOR TO THE advent of common television usage, pictures in the home became popular by the use of home-movie projectors. By a process of evolution the 3- by 4-foot home-movie picture size became an accepted one. These facts would indicate a preference for picture sizes of this order, at least for some types of picture presentations.
