An archaeologist's car containing two axes from the Ice Age has been stolen from outside a Birmingham hotel.
Mark Olly, of Warrington, Cheshire, was giving a lecture on druids at the Wellington Hotel in Bromsgrove Street, when the vehicle was taken on Tuesday.
A replica of a 750BC bronze sword, with a distinctive brass discoloration on the blade, was also taken, along with electrical goods worth nearly £5,000.
Mr Olly was in the city to talk to members of the Pagan Association.
He runs CWP Archaeology (Celtic Warrington Project), which documents all prehistoric and Dark Age remains in Cheshire and south Lancashire.
A silver case containing metal and stone objects dating from Anglo Saxon, Viking and Medieval times, was also in his blue Nissan Micra - registration C459 JTX.
The vehicle also contained radio microphones, an overhead projector, amplifiers and books with a combined value of nearly £5,000.
Two of the axes stolen date back to 250,000 BC.
Mr Olly warned anyone trying to sell the relics that all of them had been recorded.
"If they turn up on eBay or anything like that, we'll spot them straight away," he said.
Anyone with information about the theft is asked to contact West Midlands Police at Steelhouse Lane police station or the Wellington Hotel direct.
