Super-G Constellation Cutway, 1955
A fine cutway from 1955 by famed illustrator Rolf Klep, of a Super-G Constellation.
This is actually part of an amazing double-spread from a LIFE magazine, showing both this aircraft and the oceanliner Cristoforo Columbo.
Accompanying text notes that the Constellation had a flexible seating arrangement. In this drawing, tourist class passengers occupied the forward compartment, while first class passengers enjoyed reclining seats with foot rests in the middle compartment.
The Super G was produced from 1951 to 1958.
