the smallest biggest city in the world (Indiana)

Don’t let me weird title conventions mislead you; this postcard’s tagline refers to San Francisco. Nozomi picked this card up somewhere she can’t remember but of course thought of me. She asks my opinion - is it true? It’s a good question! Many people are surprised at how small SF’s population is (just over 800,000 last I checked, which makes it only the 17th largest city in the US). It has a very outsized footprint for its small population! It certainly has world-renown. I think if you asked the average non-US person to name a US city, it would be in the top five. I think it would be named before Chicago even which is the third largest city in the US. What do you think?
