Set of 7 very cool advertising Magic Lantern Slides in original shipping box. These slides were supplied and shipped from the Wheeler, Sheridan Corporation, Los Angles, Calif. to the Oestreich Bros. (Hardware Company) in New London, Wisconsin. Oestreich Brothers was a hardware store in New London that was owned by Emil and William Oestreich.. All of these slides show wear but remain in very good used condition and each one has been customized with the "Oestreich Bros." name. Five of the slides have color and two are in black and white. There is a slide advertising a pipeless furnace, portable heater, oil cook stove, padlocks, cooking range, water supply system and one of the slides advertises a contest where a prize is given for the best loaf of bread submitted. The box shows soiling and wear and some rough edges but remains in good condition. On one side of the box is an 11 cent stamp which was the postage at that time for shipping the box from California to Wisconsin..
