I saw these just the other day and considered them for an IoTD... then promptly forgot about it
The amazing thing to notice is the perspective - see how large the soldiers are at the front and how very small and far away the ones at the back are - these things are HUGE. In the Statue of Liberty there are twice the number of men in the flame of the torch than the whole remaining design (from Snopes, but only a partial quote so I didn't link).
