Bloomsbury will auction 26 original postcards of Patronus animals, with proceeds going to the UK’s largest reading charity, BookTrust. A number of famous artist and illustrators — including ‘Potter’ designers Jim Kay, Chris Riddell, Emily Gravett, Levi Pinfold and MinaLima – have contributed to the project.
The auction, which coincides with the 20th anniversary of the UK publication of Harry Potter and the Prisoner of Azkaban, will run for 10 days. For UK fans, the postcards will be on display at Waterstones Piccadilly over the next week.
