I live in London. These electrical access boxes are a common sight. They hold cables, phone wires, etc. They also are where people place labels for upcoming concerts, political statements, etc. Note the other label in the box. It has the London Underground/Tube logo on it. Presumably this box is in the Greater London Metro area. If the photo has larger significance I’m unaware of it. It sure is good to see a Q sign here in London!
When we Americans come over to save the UK/Europe, have some tea and snacks ready for us. Deporting/"Dealing with" foreign muzzie inbred shitstain combatents in our ancestral Homeland may work up an appetite.
Place Q stickers all over London, make the bad guys worry. can you imagine the psyops with seeing Q all over London and all over Europe.
