Many replicas are made of brass and some may be cast in brass with a different finish over the top. The entire set of Russian souvenir buildings on marble bases are made of solid brass. Others include, pictured here, religious institutions like churches and mosques, Egyptian pyramid inkwells, Shakespeare's Birthplace home in Stratford, England, and the Canadian Ypres WWII monument.
I collect 3D metal souvenir buildings of all places and ages. If you have any to sell or trade, contact me via my email address in the “complete profile” link at the top right of this blog.
