Uncle D and I stopped to see what this sign said on our way back from the Russian pavilion. (My aunt has a souvenir booth there... it's Folklorama time again!) Anyway, this sign was standing by a tree on the boulevard of a street that strangely happens to also be a back lane. (All the houses face the other streets that they're adjacent to.) We wondered what a plaque was doing on a back-lane street. Now we know.
