هاري بوتر وحجر الفيلسوف
Thomas Henry Taylor (born 22 May 1973) is a British children's writer and illustrator. He studied at Anglia Ruskin University. He painted the cover art for the first edition of "Harry Potter and the Philosopher's Stone". Due to the number of questions regarding the identity of the wizard illustrated on the back cover of the first edition of Harry Potter and the Philosopher's Stone, and thanks to the contribution of an Argentine named Alfonso Ferrer in Taylor's blog, in February 2016, he decided to name him Robertus Tallis.
