HELP PLEASE: Lost at Lambeth North

#Sebastian lost his #calendar at #LambethNorth tube station today. It probably won't still be there now (although I picked it up, turned it over, and wedged it beside the banister), but wouldn't it be nice if his family could at least keep a photo of it as a memory? (Sorry, not a great photo - I should have taken more but my train was coming. I now feel that was wrong and I should have missed it, but I was already running late...)

So, can we get the message out to #Sebastian, who must travel on the #Bakerloo Line via #Lambeth North tube station? It's a beautiful calendar - I suspect Sebastian (or possibly Sebastien?) must be quite young, so probably it's his family we need to find...

Our challenge for the week!
