I fancied having a look around in order to see what was available and then I came across some pretty good value pieces of art.
Adam Christopher Design Ltd
This painting is by Urban Art Studio on Etsy and the Artist is Alice. £127 with free delivery seems pretty good to me.
Another painting by Alice at Urban Art Studio and also one at great value. I don't think there is much to choose between both the paintings but it depends on a person's personal choice and probably alspo on the colour scheme chosen for the art pieces.
Pushing the budget up here with a painting from an American company called Horchow. This piece called 'Percussion' comes in a set of two and adds a touch of class with its regal blues and gold.
