Magic Lantern Story Board Metal Display Tray / Frame / or Rack Holds 56 Glass Slides 4" x 3".  These racks are 30" wide and 31" tall.  They have light surface rust so this is a restoration project.  The owner said they were fabricated in the 1880's and were professionally used for magic Lantern shows.  They are pre-cinema and very rare.  One can convert these racks to make light boxes to display your slide collection.  The size is perfect for a window display and if you have more than one this display can become a seasonal thing.  There is nothing like this anywhere else on the Internet.  Besides displaying and storing slides, the function of these racks were to generate a series of slides for story telling.  Before the pastor got these racks they were owned by a museum.   Shipping is calculated and I offer free local pick-up.  I have 17 racks so I offer combined shipping.  The eBay shipping calculator will be way off when combining shipping so go ahead and "But it Now" and I will work with you on the shipping cost.  Thank you for looking.  Ron
