The Jet Propulsion Laboratory branch of the space agency NASA recently released digital copies of some of the art work that was selected for their 2016 staff calendar. Created by the Seattle design studio Invisible Creature, the space themed travel art is clearly influenced by vintage travel posters. «The Grand Tour» is an homage to NASA’s historic Voyager spacecraft missions. The other two posters encourage vacationers to consider holidays to Saturn’s moon Enceladus and Mars. Prints are available for purchase at the Invisible Creature website.
