These paintings are all hand painted with enamel paint.Painted by IMO Australia's best artist.He was a sign collector himself and had hundreds of signs. He just passed away last year around 90 years old. These paintings were all done by him in the last 5 years and the detail is simply unbelievable.Some of the paint work is so fine and detailed it is impossible to comprehend it could be even done by hand.Cheers from the land downunder
