(LENTICULAR ON ACRYLIC SIGNED LIMITED EDITION OF 50). Magnus Gjoen has used advanced printing techniques to create a contemporary art work with a vanitas theme inspired by the Classical Era in Rome. Modern lenticular technology has brought to life the phrase "sub rosa" ("under the rose"), meaning to keep a secret. 'Roses are Dead' depicts a person whose secrets were so dark it was their cause of ruin and ultimately death.
