Some observations on the Q pic of the 2 lanterns in the window.
(And not knowing - did any anons say it was a stock photo or not?
But without knowing more: 1) the lanterns are not lit in the pic. 2) The lanterns and candles appear to have already been lit and used.(Notice the candle wax spilled in the interiors of the lanterns and on the window sash? meaning a) maybe, the signal has already been given and it is already daylight of the next day (4/19/1775)? Lexington/Concord?
Just an observation. Btw, Patriots Day will be celebrated on 4/20 Monday this year. Tomorrow.
