The world's most famous wizard is seen lunging over a pile of treasure in the cover of the seventh and final book in the Harry Potter series.
Potter's best friends, Ron Weasley and Hermione Granger, also feature on the children's edition of the book, which was unveiled by publishers Bloomsbury.
The adult version of Harry Potter and the Deathly Hallows shows a pendant embossed with a jewel-encrusted 'S'.
Author JK Rowling's previous six Potter novels have sold 325 million copies.
The writer had always planned seven books, each following the characters for one school year at the Hogwarts School of Witchcraft and Wizardry.
Rowling has revealed that two characters die in the final book, prompting bookmakers to take bets on whether Potter could be one of them.
But the text on the book covers gives nothing away.
"Harry has been burdened with a dark, dangerous and seemingly impossible task," reads the back of the adult version.
"He must leave the warmth, safety and companionship of The Burrow and follow without fear the inexorable path laid out for him."
Harry Potter and the Deathly Hallows is due to be released on 21 July.
