Because window display is recognized as advertising, the ceaseless work of the master window dressers upon the outer rim of the Macy store comes under the direct supervision of the advertising department which in turn reports direct to no less an authority than the triple partnership itself. Publicity is the great right-arm of the super-store of the America of today. Publicity not in one channel, but in a thousand. Macy's not only helps to dominate the advertising pages of the newspapers of New York and a good many miles round about it, its red star not only gleams in Herald Square, but in these very recent days upon the high-set electric hoardings of Times Square that blaze forth far into the night; it finds its way into the public thought here and there and everywhere. And yet, with due appreciation of every other medium of publicity, the street window of the store still remains one of the most important phases of its appeal to possible patrons. Its displays are scheduled long in advance; are devised as carefully as the decoration of a home might be, or, better still, as Urban or Pogany would plan the stage-settings of a scene in the Metropolitan or at any one of the various "Follies" that one finds just north of the Opera House. A large staff of men is kept constantly at work dressing the windows, and this staff includes the carpenters, paper-hangers, painters and electricians who are needed to help prepare the special exhibits. Under the floor of the window next the principal entrance on Thirty-fourth Street there is a tank, which is used when a pool of water is required to carry out some scenic effect. It is capable of floating a canoe to suggest the joys of camping and the need of going to Macy's for one's vacation requisites--as well as for use in other capacities. Known in the store as the "parlor window" it has been made to represent pretty nearly everything from milady's bedroom to a glorified carpenter shop. Window displays are regarded by Macy's as an important auxiliary to newspaper announcements. Very recently, during the few weeks before Christmas, a sale of overcoats was advertised. All the windows were then dressed with Christmas merchandise, but from one of them this was all removed and the sale overcoats substituted. For one day only. For upon the very next one the Christmas window was returned to its holly and mistletoe flavor.
