The artist celebrates a decade with Castle Fine Art – and his upcoming 80^th birthday – with eye-popping new limited-edition silkscreen artworks and sculptures as the latest instalment of his acclaimed Born on a Rainy Day collection. The new silkscreens are made in bold, dynamic colours, making them just as colourful as the personality who created them.

There is a new stainless steel tabletop sculpture of ‘Hang Gilder', his drawing featuring a winged figure in a meditative pose , and in a first for Billy, his ode to the Clydeside welder, ‘And on Monday, God Made the World’ is available in a monumental 1.7 metre-high sculpture.
