A tram would be nice (I really like the look of the trams in Lisbon) and that train hand cart would be a great addition to the Western theme

I really love this topic

A Dutch windmill would be amazing!!
Although I don’t see them doing that unless they are going to do some country themes. If they would combine the windmill with the Dutch lady from mystery figures series 15 70026 it would sell really great in tourist shops. They even have a small market in Michigan

(I recently discovered that there’s a Dutch windmill the Swan (de Zwaan) that got sold to the city Holland in Michigan in the 60s. The people from Vinkel were really missing their windmill so they build a new one.)
Oh and there is also a Holland theme park in Japan

Perhaps they can sell it there too.
What sort of set or items would you really like to see from your countries?
