Here is the most precious # niche plamo in my collection . Midget house of Tamiya. A styrofoam model born in the transition from wooden to plastic model with an item more than 50 years ago. Although it is in Tamiya historical hall in Shizuoka, personal possession is rare. Mr. Tamaki Tamiya, current chairman, said in a book “It could not be sold at all”.
