For the last two Father's days, I draw Guns on my dad's card since he and I love guns. This year, I decided to do something different. He loves German Tanks, so I thought that would be a good subject. Looking through Wikipedia, I came across this, the Landkreuzer P. 1000 Ratte. One look, and I instantly chose it.

The Landkreuzer was going to be the largest tank ever built. It's main gun was taken from a naval battleship and had almost impenetrable armor. Unfortunately, it's large size meant it would crush bridges, couldn't be transported by train, and couldn't go through tunnels, so some German officer with more Brains than most of the Nazis wisely cancelled the project.
