Spot the error

Helsinki has some very appealing architecture and I've always been rather fond of this particular building. While it lacks the ornate detail of the Jugend houses, the reserved pattern adorning the side complement the overall design of spare lines and angles. As I was admiring the building one afternoon, I noticed a mistake in the pattern which may have been accidental or possibly even intentional as an Escheresque illusion. I prefer to think it's the latter since I think it lends a bit of cachet to the building. :)
