I love me a charity shop and I was in one the other day and I randomly said to my mother 'I think we need a new pic for your husbands room 'cause the deers are old'. I went to the picture bin and found an oil painting in a semi decent frame signed by an artist called Alan Thompson, it was about 45cmx30 so not small small. It was a beautiful painting of a river and scenery, all very pink and green which was ideal for the bedroom and for the bargain price of £3!
When I got home I thought I'd google the artist as it had his card still attached to the back and I couldn't believe it when I saw a lot of his paintings sell from £600-£2.5k.......
Obviously not selling it but it's good to know that some good buys are out there!
