A feww weeks ago I posited that the hand could have been a negative, flip, and re positived ... Stanley's right hand used to generate a left hand, based upon the positioning of the first and second finger as relating to the position and shape of the thumb.
Got it! The image of the wall by itself shows the joins are off-set, not one beneath the other. How sloppy! How stupid to 'they' think we are?
I agree with you about the hand. I gather if it was reverted to the original, what you would end up with is his 'other' hand exactly.
Hey...and the vertical grouting between the blocks looks as if it’s been added. Compare to the image of the wall by itself, and see how neat the grouting is!
