The mountains grew from the valley

Jozef Murgaš has such a commemorative plaque located at the Main Post Office in Bratislava. These days, a book by Jozef Vranka with the title was published by the ARIMES publishing house The mountains grew from the valley .

It is the second supplemented edition of this one and also contains samples of the patent documents of Murgaš's inventions.
