The stamp issue voted most popular in this year’s poll is Silo Art, designed by Janet Boschen Design. The issue taps into the recent phenomenon of painting extraordinary artworks onto the towering grain silos dotted around Australia’s rural wheat-growing towns. The epic artworks featured on the stamps were created by renowned street artists. Guido van Helten created four towering figures at Brim in Victoria’s Wimmera district, each figure sheltering from the heat and dust. Drapl and The Zookeeper painted aspects of the south-west Queensland town of Thallon across a massive silo, including the region’s spectacular sunsets. The silo mural at Ravensthorpe, Western Australia, Six Stages of Banksia baxteri by Amok Island, depicts this endemic floral species as well as some of its main pollinators. For the Weethalle silo, in New South Wales, Mongolian-born Heesco Khosnaran chose to represent the district’s main agricultural activities: shearing and wheat growing, inspired by local photographs.
