I just noticed this Ebay auction for an original Nick Walker painting titled Vandalism. The auction still has 5 days to go so enough time to contemplate whether this artwork might be worth the price of £ 3 300. If that price is a bit steep, you can also have a look at some of Nick Walkers prints on Ebay.
I’ve been sifting through some of Nick Walkers art and noticed one seller describing him as “like Banksy”. While that comment may be a bit cheapish it does make it clear that Nick Walker is a British street artist who has been picked up by galleries.
