a sense of security and reliability

People come and go but stone endures. Pity that after some time only the marks of tools bear witness to the stone’s heritage and effort invested in working it but offer little information on the people involved. But there are documents revealing some information at least of commercial activity of the past: at Poznań’s „Stone“ Trade Fair (held from November 18th to 21st 2015) shares and bonds of natural stone producing companies of two centuries were on display.
