INVISIBLE CITIES XIV -- Cities and Memory: MAURILIA

1. Why do the inhabitants prefer the city represented in the postcards?  What influence does the nature of the postcard have--on the city, or, generically, on anything?  Is there a difference between a postcard and, say, a regular photograph in its ability to depict a time or place?  What would happen (stay with me here) if memory worked both directions, toward the future as well as the past, and there were postcards of present Maurilia available for past Maurilians to examine?
2. For some reason this reminds me (story and movie) of Benjamin Button.
3. The second paragraph of the vignette discusses how two cities can exist simultaneously--two cities which are one city: one place, one name (same citizenry??), two cities.  Maybe this is going out on a limb, but if each vignette is a puzzle piece, what clue might Maurilia offer toward anticipation of the final, completed picture?  Does it have to be just two cities in one, or could the number be even potentially infinite within the confines of one geographic space and one name?
4. By extension (and this against the end of the first sentence of paragraph two), is it possible for there to be two or more people with the same body and the same name (and no, this is not an issue of schizophrenia or multiple personalities)?  And further, families, schools, countries, teams, gods, etcetera?
5. The final lines of the vignette tie back to the first question: is it just the nature of the postcard, that it describes a fiction rather than a reality, or is there truly a second city existing in the same plane and plot as the other Maurilia?
