Gallery 9 took part in Art on Paper Amsterdam for the first time. It was successful for Duifhuizen. He sold several works of art, including 'Ode to Jane', a variation on a work of art by Jane Leeuwenburgh. Jane was a 'master of minimal art' but didn't get the stage she deserved in her life. In addition, he sold Acquired Brain Injury related art to someone who also has ABI.
