A magical dream for Muggles: J.K. Rowling's chair is heading to auction.

The chair was where the author sat while writing the first two books in the Harry Potter series.

You may have to visit Gringotts Bank to pay for it. The opening bid at the Heritage Auctions sale next month starts at a whopping $45,000.

The chair is being put on the block by an anonymous seller. It is one of four from Rowling's flat in Edinburgh, Scotland.

It is signed by the author in gold and rose colors.

Rowling painted "I wrote Harry Potter while sitting on this chair" on the seat.
