Presenting the A320neo in the colours of American Airlines in the 1950s. This livery in general captures the look of American Airlines aircraft essentially from the company's inception until the early days of jet airliners, which featured bare metal accented with an orange lightning bolt. 

This livery in particular captures the look sported by American Airlines DC-6's in the 1950s and 60s and sports the name "Flagship Maryland" which appeared on the real life aircraft N90717 and served American Airlines from May 1944 until November 1966.
