I was considering doing something very similar with my anniversary edition. I decided on the landmarks I wanted (very similar to both your lists) but never had the time to actually CAD the models and get them cast. Depending on the level of detail, some of the buildings could take a while to model out.
Ossel, if you’re willing to put the time in I would love to get some nice city markers. Even if you can’t get someplace like HBG to make them for you, you could always get them printed from Shapeways. shapeways.com Put them up for sale and maybe even make a small profit. I know i’d buy a set.
Anyway, here’s my list:
USA - Washington - White House
USA - Honolulu - Aloha Tower (alt-Iolani Palace)
USA - Manila - Dr. Jose Rizal Monument
USA - San Francisco - Golden Gate Bridge
Germany - Berlin - Brandenburg Gate
Germany - Paris - Eiffel Tower
Germany - Warsaw - Wilan�w Palace
UK - London - Big Ben
UK - Ottawa - Parliament Hill
UK - Calcutta - Victoria Memorial Hall
UK - Hong Kong - Wong Tai Sin Temple
UK - Sydney - Sydney Harbour Bridge
Japan - Tokyo - Sensō-ji (AKA-Asakusa Kannon)
Japan - Shanghai - Yu Garden
Russia - Moscow - St. Basil’s Cathedral
Russia - Leningrad �(St Petersburg) � Winter Palace
Russia - Stalingrad � Old Steam Mill
Italy - Rome - Colosseum
