Lord of the Rings fans will be able to bid for a piece of history when parts of a sculpture marking the city's links with JRR Tolkien are put up for auction on eBay.

The 20ft-high statue, which depicts the fictional tree-like Ent creature from the trilogy, will take root in Moseley to remind Birmingham of its most famous author.

Planning permission has already been granted for it to be located on the Moseley Village Green, but designers need #80,000 for its construction. To fund the artwork, the Moseley Statue Group has been selling individually wrought and engraved gold and silver-coloured metal leaves.

These will feature in the artwork at the foot of the sculpture, with 370 auctioned on ebay.

Bidding will begin on Sunday, with a #500 "buy now" reserve price for 20 leaves. After the initial auction, 50 leaves a week will be put online for seven weeks.

Each leaf will have a special dedication made by Tim Tolkien – the author's great-nephew and the artist behind the structure.

Mr Tolkien said it was important for the leaves to be sold to ensure the statue is constructed. So far, 30 have been sold.

"The bottom line is it is not going to happen unless we sell the leaves," he said. "We have got planning permission and the support but unless we raise the money needed for the sculpture, then it is not going to happen.

"There are no other sources of funding, so if people want the sculpture to happen to commemorate JRR, then we need those leaves to be sold."

Larger bronze leaves are also available for corporate sponsors and private donors, he said.

Speaking about the eBay launch, Moseley Statue Group chairman Mark Guest, added: "Given the interest we have had, it is going to be very exciting and we are quite hopeful that we should have this next summer."
