Wonder which one that is...the beautifully restored NATMUS one or the 'Fido' one that sold at BJ a few years ago?.
Close to 10 years ago I laid a copy on the NATMUS resto guys of an old GM booklet I have detailing the Futurliner Parade visit to Canada in 1955...they were all happy as it has the only known shot of all 12 Futurliners in one picture!.
The Futurliners and Parade of Progress is an interesting part of GM history also the units as known today are way better looking than their original bubbletop configuration.. New style tops and side fluting was updated in the early 50's largely in part to reduce the heat in the bubbletop cabs..
Here's a crappy pic w/ the old bubbletop..
