Thanks for joining umbclibrary for our takeover! We leave you with Special Collections librarian Susan Graham's favorite item--the stereoviewer. This 19th century technology is used to view 3D images, such as this one of Druid Hill Park. Be sure to follow us for more #ArchivesMonth for the rest of October and other library goodness all year round! . . . #UMBCarchives #stereoviewer #photography #3D #librariesofinstagram
