Abstract
A slide projector assembly provided with novel slides which may be drawn upon and/or associated with a sound track specific to the slide being projected. The slides may be blank or have line drawings in which cases the slides may be drawn upon. In addition slides, either of the type set forth above, or of a more or less conventional photographic slide design, may be provided with unique machine readable slide identification means. A housing, which includes slide projection means, is also provided with slide identification reading means so that when a slide is placed in the slide receiving means of the slide projection means a recognition signal will be transmitted. This signal will be received by an audio recording and playback means which may initiate either the playing of a sound track or may set a flag at the beginning of a sound track which is to be recorded.
