Excuse me for not writing sooner. write and tell me all the news at the shop.
I'm not sure about the sender - it looks like Leaota, which is the name of a mountain range in Romania (though there is a FB page for someone named Laeota). There were many postcards in the set, all addressed to a Miss M[aude] Graham. Lambton Mills was a small village on the Humber River in what is now Etobicoke, Toronto. There is not much left of the settlement except for The Lambton House Inn. And a cemetery, though there is no listing for any Graham. This card was mailed on August 18th 1909 but by 1915 the village was destroyed by fire, save for the Inn which was the only brick building. Makes me wonder what the shop was and what became of it and the shopkeeper, Maude.
