A very rare, large and impressive medal.
The rarity is confirmed by the fact that the item is unlisted in Witold Garbaczewski's catalog devoted to these issues entitled "Industry - Art - Politics. Economic exhibitions on Polish lands and with Polish ties circa 1850-1914."
Minted in white metal (according to spectrographic analysis, the main components are 62% copper and 24% zinc).
Beautiful state of preservation.
First time in our offer.
Diameter 60.5 mm, weight 89 g.
