In 1991, as a sequel to his highly-acclaimed Visions of Space, Hardy produced The Fires Within: Volcanoes on Earth & Other Planets, with text by Dr. John Murray. A number of the paintings (many in oils) may be seen here, and Original Art is available for several of them. It was originally planned to hold an exhibition of these at Birmingham's Science Museum, and a number were framed; but then the excellent Museum was closed and replaced by the Think Tank – largely 'interactive' exhibits for children. . . Which is why these paintings are now available.
