The magical world of "Harry Potter" has joined forces with the U.S. Postal Service.

Just in time for the holiday season, the USPS announced on its official website this week that a souvenir booklet of “Harry Potter” First-Class Forever stamps will be released in the coming days. According to the announcement, the self-adhesive stamps, based on the best-selling boy wizard book series of the same name, will contain 20 commemorative images.

While the booklet is not currently available for purchase, fans of the J.K. Rowling books and ensuing blockbuster films are able to pre-order the collectibles on the USPS website. The stamps, which retail for $9.20 per booklet (46 cents per stamp), will go on sale Tuesday.

“Anyone who collects anything about Harry Potter will want this in their collection," the executive director of the USPS stamp service, Susan McGowan, told USA Today Tuesday. "We anticipate a big demand for these,” she said, confirming that 5 five million “Harry Potter” booklets were produced.

The first images of the stamps, which show the films' star Daniel Radcliffe in his best Harry Potter garb and his sidekick, actress Emma Watson, as brainy Muggle-born witch Hermione Granger, were revealed on the "Today" show Wednesday. According to USA Today, each of the 20 stamps will feature different characters (and creatures) from the stories with three rumored to be featuring Voldemort, Dumbledore and the Weasley brothers.

According to Warner Bros. Consumer Products President Brad Globe, the studio behind the film franchise approved the release the stamps in honor of the scene from the first book and film, “Harry Potter and the Sorcerer’s Stone,” when Harry receives his letter to attend the magical school of Hogwarts via owl mail. "In the books and films, Harry Potter's life changed with a letter, so we couldn't envision a more fitting tribute to commemorate the world created by J.K. Rowling and brought to life in the Warner Bros. films," said Globe. “We think fans around the world will share our excitement in seeing the films take their place alongside the most significant figures and events in history as part of the U.S. stamp program."
