You never know what you'll find when you tear a business down, but what they found inside these walls was a shocker!

Boise Pottery is set to open shortly, but they just discovered as they started construction at 3831 West Chinden Boulevard old wooden crates labeled mine and anti-tank!

According to KTVB the boxes are from WWII. Who knows how they ended up inside the walls because the building wasn't constructed until 1959, well after the war.

The boxes were empty, luckily, and the crates will now be disassembled.

Another interesting point is that the original instructions on how to place and operate the anti-tank mines were found inside the boxes.

The building was formerly Garden City Furniture and any boxes that are salvageable will be auctioned off to collectors.
