Ceramic Characters by J.Ace

I have recently discovered the name of the artist responsible for several small mask and character face figures pasted up on east London's streets over the past year. The little figures were not accompanied with an artist name, but I have discovered the artist behind them from the power of the Internet. There were several more of these masks around, so please let me know in the comments where they are located. The artist behind the figures is known as J.Ace.
