Everyone is familiar with James McNeill Whistler's masterpiece, "Whistler's Mother." Legend has it that Whistler's original model was a no-show, so his mother was a last-minute stand (sit) in. Sheffield artists have collaborated to document the lesser known artwork - Whistler's mother during her morning SuperTram journey, pulling into the Cathedral stop. She's just finished her snack: a packet of Hendo's Yorkshire crisps and a can of Abbeydale Moonshine.
