Overlaying the EMB pics based on BIG BEN

Each EMB pic has been layed onto the pic that preceded in the drop sequence of EMB pics as a series. However, in this version, LisaMI6 is layed down first because this version of the overlay is based on BIG BEN and in LisaMI6 Big ben appears larger than in the other EMB pics. That difference in scale has been used here as a marker for the purpose of overlays. LisaMI6 is the last in the London Pics in the drop sequence. Hence it appears in this version of the overlay both at the start, as a reference for BIG BEN, and at the end as the last.

Overlaying is used here to look for clues about details that might distinguish one pic from another and also to look for clues about details that might be common or that connect one pic with another. This technique can be extended to other combinations of London Pics. Here, for example, ROT3 has been excluded for the sake of focussing on the EMBANKMENT as a distinct location featured in the drops.
