The head is listed to sell for between £5,000 and £10,000
A waxwork head of ex-Beatle Sir Paul McCartney has gone on a magical mystery tour after it was left on a train.
Businessman Joby Carter had collected the model of the mop-topped sixties star to be auctioned on Sunday.
In a desperate bid to recover the item, which is listed to sell for between £5,000 to £10,000, Mr Carter has offered a £2,000 reward for its return.
The head was left in a bag under a seat on a train from London at Maidenhead station in Berkshire on Thursday.
The service would have terminated at Reading.
Mr Carter said: "It was just a silly thing to do, if it wasn't so critical to get it back for the auction it would probably be quite funny.
"So far, we've had a lot of hoax calls from people claiming to have seen the head but nothing concrete.
"Someone may have just picked it up and thrown it away without realising what it was or someone might be trying to sell it.
"I've put up the reward and am desperate to get it back."
The waxwork model was made in the 1960s and displayed at the Louis Tussaud's museum in Great Yarmouth.
Carters Entertainment auctioneers are auctioning it along with other fairground memorabilia in Maidenhead.
"The silly thing is since the appeal to find the head we've had more bids come in and the sell price is guaranteed to have gone up.
"But until it is found it is worthless," Mr Carter added.
