These are the only two booklets/magazines we haven’t nailed down identification on but they appear to be produced by the same publisher and probably directed towards school age children. The are loaded with black and white photos of trains of all types for this early period.
The book with the large train front has a fully taped spine cover and the cover is separate from the book. The book portion is in great shape with less then expected reading and age wear and is otherwise tight.
The other book with the great shot of a Japanese child playing with a scale train is in fantastic condition with the signs of its age showing mostly in the form of surface dirt on the covers.
