San Diego Comic-Con is getting a little more magical this year. Entertainment Weekly showed off a new Harry Potter poster, celebrating the series and character’s evolution over the past 20 years.

You can pick one up from Scholastic, if you attend the signing with Jim Kay (Harry Potter illustrated editions), Brian Selznick (20th anniversary edition cover artist), Kazu Kibuishi (Harry Potter 15th anniversary edition cover artist), Arthur A. Levine (American editor of Harry Potter), and David Saylor (creative sirector for the Harry Potter book series) on Saturday, July 20 at 11AM in Sails in the Autograph Area at AA19. No ticket is required – simply show up!

Then, following the panel, you can also catch that group discussing the process for illustrating the Harry Potter books over in Room 6DE from 3pM-4PM.
