...A TRYPTYCH...
This is one of those trick questions, can you spot the differences between these three images?
Image 1 on the left is from the 1958 Inquest, this is the version that has 122 pages and not 102. It contains images of all of the exhibits including two close-up images of the plaster bust. Image 2 is a standard front-face image of the bust in situ at the SA Police Museum and image 3 shows a disembodied hand supposedly retrieving hair samples from the eyebrow area of the bust.
There are a few differences some of which could be explained away but at least two are markedly different. You may want to compare some of the other images of the bust, plenty of them on the web.
Over to you...
I am supposedly having a break...
