Sent my way by long-time correspondent, Kyril Negoda. I’m not entirely sure of the vintage of this, as the archive it resides in covers the entire period from 1980–2000, and none of the images have dates attached to them. There’s definitely an early 1980s vibe to it, though – mainly from the tightly kerned Futura Bold heading at the top.

I’ve seen transit map-styled airline maps before (here and here, for example), but this one stands out as being particularly attractive and boldly designed, as an advertising poster should be!
