I have'nt a clue where it is. However, if you look closely in the top left hand corner you will see that one of those slates, albeit a small one, appears to be very loose. I do take it therefore, A-B, that you have done your civic duty and informed HBC of this perilous state and the clear and present danger above the streets of Accy. It would be a credit to no-one should that slate come off the roof and decapitate some old lady while the rest of us are here pondering its whereabouts.
