Stirling Street Art

Spent some time in Stirling on Friday and, for a wee change, decided to walk back to the Park & Ride at Springkerse rather than take the shuttle bus. I saw this piece of street art on the pavement leading towards the railway station - don't remember noticing it before, though!

The wolf is the ancient symbol of Stirling, while the old British Rail symbol is clearly seen on the bottom left of the 'painting'. Don't know much else about the art-work otherwise, however.
