Ron Weasely's Howler from 'Harry Potter and the Chamber of Secrets' is up for auction!

An envelope used as a Howler in the second Harry Potter movie - bearing a gold-coloured Weasley wax seal - accompanied by an autograph of actor Rupert Grint may fetch up to £5,000 at an auction in the UK.

The envelope is made of a red card with a cream printed label addressed to 'Ronald Weasley, Hogwarts School of Witchcraft and Wizardry'.

A length of burgundy ribbon is wrapped vertically around it, and fixed at the back with a gold-coloured wax seal bearing a 'W' for Weasley, which is still intact.

The letter, used in the movie Harry Potter and the Chamber of Secrets, features the text of the Howler printed in a calligraphic font.

In JK Rowling's fantasy series, a Howler is a magical letter in a red envelope which shouts out the written message into the writer's voice.

Also included is an 8x10 inch still of the scene in the movie, autographed by Grint, who plays Ron, in silver pen.

The lot contents remain in good condition, with some glue residue present following its professional removal from a display, while the backup letter also exhibits some slight fading, according to the Prop Store Auction.

The envelope includes a letter of donation from Warner Bros.

Other items in the auction include a set of a jacket, cap and a canvas bag autographed by Daniel Radcliffe, a 30x40 inch poster signed by Radcliffe, Grint and Emma Watson.

The bidding for the live auction will take place on September 26.
