Follow the heads. Counting clockwise from the "A", the fifth boy has his head right on top of the line. When you shift to position B, the bit of the head on the outside becomes part of a hand.
When I was an infant, I went to school one day and there was no free milk, "Maggie Thatcher, milk snatcher" had put a stop to that. I've always hated the woman, and now you've made her worse ...
In general people who demonise Thatcher largely agree with her on many policies. They are generally pro EU (she campaigned to remain in the referendum on EEC membership in 1975), they are usually opposed to reopening coal mines, or nationalising BP (or BA or JLR) or making telecommunications a state owned monopoly. To be fair they might favour nationalising utilities and train operating companies, but that is about it. They rarely disagree with her that climate change risks "irretrievable damage to the atmosphere, to the oceans, to earth itself", and are unlikely to want to bring back the use of CFCs.
I wish there were an easy way to rotate the image back. I can use the inspector in dev tools and manually change the transform style that's applied, I suppose.
