Noted for his pen, ink and watercolour illustrations, George Butler has drawn praise for his artistic interpretations of travel-led locations and current events, with Butler's work regularly appearing in various publications including lifestyle monthly, Monocle. Butler's five illustrative T-shirts take their lead from Gloverall's rich and diverse history, reflecting the duffle coat's association with vintage motor racing, anti-establishment groups in the 1960s, WWII era motorcycle mailmen, naval officers and sporting event spectators.
