Over the last year, Netherlands-based artist Jeroen van Kesteren has been toiling away at these sculptural airships as part of a series titled Orphanage for Lost Adventures. Made primarily from cardboard, aluminum foil, adhesives, and an assortment of papers used for sails and propellers, the whimsical flying machines have a distinct steampunk feel. The pieces range from 40 to 50 centimeters tall and take about a month to make. Jeroen shares additional images of the airships and several additional sculptures on Pinterest. More
