Cover art for Mansard Roof lyrics by Vampire Weekend

bentuthill - that's a genius analysis regarding McDonalds - they have mansard roofs, and the their "salty" signs do hang in their eaves. Plus they obviously are surrounded by garbage and concrete.

I guess the lines "The ground beneath their feet Is a nautically-mapped sheet As thin as paper While it slips away from view " could refer to how a country (Argentina) can mark a territory as theirs on a map, and invade it, but it can be as quickly taken away - their stranglehold on the territory was as thin as the paper the map is written on.
