I knew this looked familiar so I looked it up. It's the Three [Black]Smiths. From Wiki: "The statue was damaged in a bombing during the Continuation War in 1944. Marks of the damage can still be seen in the base of the statue, and the anvil has a hole caused by a bomb shrapnel."
However, I'm with @DPittman now that I know what the statue depicts. Blacksmithing in the nude seems wrought with danger (pun intended).
