Hello fam. Been a while. UK bread anon here to share a VERY intriguing photo an anon just found which may have been taken on the SAME EVENING as the LisaMI6.png pic posted by Q.
Observe the pattern of office lights on the MILLBANK BUILDING are the same in both photos.
The pic just found was, as stated by the photographer, submitted for the Photo24London contest sponsored by Nikon. The competition ran from 12pm 20JUN2014 to 12pm next day.
Now if anons will agree that the building lights in both pics are a compelling match, then we have a definite "bookend" to indicate that LisaMI6 could not have been taken after 20JUN2014.
HOWEVER... observe that bit of white illuminated construction shrouding on one of the towers on WESTMINSTER PALACE (behind Big Ben). Our extensive research into that refurbishment, of that particular tower at Westminster shows that the work done there, and evidenced by said shrouding went on from the beginning of NOV2013 to mid-APRIL2014. Other evidence leads us more closely to a currently suspected time period running from after ST. PATS DAY 2014 (17MAR) to mid-APRIL 2014 when that shrouding came down. Numerous facts have gotten us to this point to include: subsequent major road contruction/changes occurring in the Summer that year, a missing traf cam in a St.Pat celebration vid on 16MAR, advert signs on the gangway of RS Hispaniola, the appearance/replacement of blue Boris bikes with subsequent red Santander bikes, the apparent green appearing in the trees which leads away from Fall/Winter to early Spring new buds on trees.
An unrelated but no less interdasting development is another sign (marker) found for the CORINTHIA HOTEL pics which dates that set to BEFORE 2MARCH2014.
That evidence is in the form of a small temporary sign showing a first-aid sign in green and white which we feel may have been placed there for a special event such as a marathon. This may have been for the StPat Marathon. Moar on that marker later.
