Mystery signs in Midsomer Norton

Has anyone else spotted the mystery signs on the Greenway in Midsomer Norton?

I was going for a stroll yesterday and spotted two quite random and funny signs on the path.

One points in two directions and says 'Here' and 'There'. The other just said 'This sign is not purple'.

Do we have our very own Banksy in our midst?! Well, perhaps not, but I'd be interested to know who is behind them?

I spotted one about half way between Midsomer Norton and Radstock, and the other near the grassy area where there are jumps for BMX bikes.

Anyone else spotted any of these signs? Tell us if you spot one!
