Through the keyhole

A long and challenging day in London today - and another tomorrow. I struggled with a blip again today. I found a fantastic shop for blinds and curtains with the most remakable collection of knobs on display in their window ... but the window was too filthy so their day of glory is yet to come.
Walking back I saw this (green) plaque and I couldn't help but wonder what this house was like in 1891 - has much changed behind that black door? I also wondered if I can set up my own "Society", maybe a blip "Society" and get plaques put up all over the place to celebrate blippers worldwide?
I think I need to get out more.
Mini camera today DD - sorry no 40mm pancake
