I'd expect them to exist in various degrees of hand-drawn sophistication
before being productionised by an artist rather than a designer.

Perhaps recliner can tell us if this map was ever a public document
circulated by the airline.

I don't know, as I just spotted it on Twitter.

Of course, one explanation is that it's a draft commissioned as part of
the process of producing the Maholoy-Nagy poster (which contains a
substantial geographic representation of the routes, as well as the Beck
insert).

The mileage numbers of the Beck map won't necessarily have been easy to
research independently, so perhaps he was a subcontractor for the bigger
project.
