Very interesting set of 8 glass glass slides with period labels. There is some damage but most are still quite usable. The first attached image shows the grouping with the box in which I received them. The box metal reinforced corners to protect the slides, two of which are missing from the inside portion of the box. The second image is a slide showing U9 returning to port from an apparently successful voyage. Missing material from bottom left corner and a light crack above that. The next slide is undamaged and shows a well known portrait of Otto Eduard Weddigen who commanded the aforementioned U9 and who was killed in action in 1915. The next image shows the famous Emden in 1914. There is an old fracture in the glass on the right side top to bottom. The next slide is undamaged and shows a brisk naval engagement but the label is incomplete and I can identify little (But great artwork). The next slide is Karl Friedrich Max von Müller who commanded the commerce raider Emden (Shown on another slide). Unfortunately this slide is heavily damaged. The next slide shows a column of warships apparently looking for business. This slide is in fine shape. The last image shows two slides, one showing the sinking of the Abukir and the other a peaceful harbor (I think the label says Kiel). A few of the slides are indeed damaged but most are fine and I do think this is a historically interesting lot with some very nice artwork.
