Copper cut from 1973

I was cleaning the log cabin and found a copper engraving depicting a historic battle

it was made by my dad in 1973 when he was young he loved historical events and this metal copper so he made engraving an interesting technique

shows fencing horses fighting peasants life and overbearing greats

and his time signature work that I was able to save in my childhood because someone wanted to end it in the trash but it was an art piece.
Now it is preserved to decorate the apartment
