The original of this cartoon of Greta Thunberg is drawn in felt tip pen on the back of a Playmobil movie poster, size A1+. At the market stall I run on weekends it often inspires comment and discussion. Most people seem to like it, and seem to like Greta, but there are those who dislike her and her message. Interestingly, the most critical have been older women.
