Dear Columbine,
thank you so much in helping me to solve this mystery! It seems that on the postal cancel is another year than 1959 (19-16?), and I think that a year 1959 is when someone added additional note (maybe some previous researcher from that time?). However, I am not sure that it is a actual year on the postal cancel, but it looks like it is. And all this drawings and paintings in the book looks to be made a much before 1959 (probably in the first half of the 20th century).
I made a scan of the front page of the postcard for you, there is also some interesting notations...
Maybe, but only maybe, if you look that on the first post stamp was glued another... and address written in English is also added later... Maybe someone 33 years later send again the same postcard... He (or she) just glued actual post stamp over the used, added a new address on English, and resent again the same postcard???
