Big Country

Last year C brought home this flag from his trip to Nova Scotia. I assumed it was the flag of Nova Scotia, but I should have known from the word assume that I would be incorrect. This is not the flag of Nova Scotia nor is it the flag of any other Canadian province.
It's not the flag of Gambia, Estonia, Kosovo, Palau, Brunei, Cameroon, or Lithuania. In fact I couldn't find it in our Smithsonian Handbook of Complete Flags of the World.
Does anyone recognize this flag?
