international street art in nelson??

so we stumbled across an area in nelson that had some graffiti in it and we saw these... now they're quite rough and we were wondering whether it was actually akroe and andre's monsieur A creations... must have been, but a tad unsure as the richmond park down the road is full of rough as banksy rip-offs... all g, if they are the real thing, awesome, paris in nelson...
