BAIRD LABORATORY LECTURE SLIDES  --  1920s

Presented below are an assortment of fifty (50) glass lecture slides used by Scottish television pioneer John Logie Baird.  All are believed to be produced before 1930, although there might be a few exceptions.  There is no way to know the exact order of the original presentation, but I have attempted to group them into similar topics.  Several have never been published.  (Courtesy Early Technology Library, Scotland)
