The Flight to Tangier

I seen this movie a thousands of times ,It is great.It wasn't until years later that I learned it was in 3D.This movie never looked That way ,cause the focus is purely 100 percent plot and story.I also suspect that the trailer was originally in 3D,whether it exist or not that is a question.In a short about the history of 3d a image of the left an right film of the movie was shown and ,boy, those Technicolor dies hold very strong ,no pink fade .This could be a worthy choice for Blu-ray 3D,in the future ,although I think it's public domain,It could still be put out on Blu ray 3d.
