This is a piccy I came across on the web of a gentleman standing in front of a Panther at Bovington Tank Museum.
The shot is straight on so you can see the huge size of this mechanical monstrosity.
I couldn't resist putting a Warlord 28mm infantryman in front of my Corgi 1:50 scale Panther. Again the shot is straight on.
You will note that on his base the miniature is slightly taller than the real person. Now the gentleman above is almost certainly significantly taller than a 1940s European.
Draw your own conclusions, chaps.
