Curiosa: The world beneath your feet

Did you know that Scandinavia has some of the prettiest manhole covers in Europe? Are you surprised to learn that Italy's manhole covers are merely functional while Spain's and Germany's burst abound with civic pride? Would you be somewhat disturbed to read that "Netherlands manholes reflect the nature of the country's inhabitants, efficient, tidy but rather dull"? Then this illustrated international survey of manhole covers is for you, my friend. (Brought to the Intarwebs by one of the editors of the Exeter Working Papers in British Book Trade History, which is how I found it. I'm a rare books cataloger, Jim, not a manhole cover aficionado).
