Bertram Mills Circus III: The Grand Show in 3D and Final Thoughts on All 30 cards

In this third and final part of a series on VistaScreen's stereoviews featuring the Bertram Mills Circus, we look at the inferior (but scarcer) "Night" version of Series 46, which replaced the "Day" version at some point in time. We also look at possible times these photos were taken, the performers who appear in them, and the problems with shooting on slow glass plates in the dark.
