around 1853, the first of the J. B. Dancer (inventor of the process)
Miniature Photograph Slides became available, growing to a numbered
series of several hundred images over the next twenty years or so.
They featured photographic images of famous people, art works,
buildings, geographic landmarks, etc. Eventually, other
individuals, as well as Dancer, produced and sold these popular
types of slides with tiny
photographs that were only visible with the aid of the microscope. They
remained popular on into the 1890s when interest in them waned, and
production ceased. All slides shown are 3" x 1".
