http://wwwphilatelie-truchtersheim....z/japon.htmlNice cover with some math. In any direction ,vertical,horizontal,
diagonal if you multiply the values you always come up with 1000.
For example the bottom row 50 x 4 =200 x 5 =1000 .It works everytime.
The question posed by the person who posted this cover in the above forum was ; Why were the stamps placed like this?
1) has to do with math ?
2) just by hazard ?
3) will be told about it later...
