2416. St Werburghs tunnel (95)

In the depths of St Werburghs tunnel is this fine piece of writing by Nevergiveup (NGU) which I think, but am not certain, spells out ZBOK. The colours set on a contrasting dark background work rather well in the difficult artificial light of the tunnel.

NGU has created horizontal layers in his letters which blend seamlessly from top to bottom. Those of you who recognise the name will know this artist as the creator of #followmyrabbits which have made dozens of appearances on Natural Adventures.
