PLAN No. 741. HIDDEN COIN IN WINDOW
This is an old plan, but to those who have never seen it worked it might be suggestive of some idea.
The merchant increased the value of his store windows by means of concealing a coin or some other object and awarding the person who finds the article, a certain prize. You would be surprised at the amount of interest this attracts to a display window, and it often brings many sales. At least, it has the effect of making the windows far better advertising mediums.
