I embarrassingly bought over £7,000 worth of "Tell Brak" idols from Antiquiti (Mike Davis). These were recently listed on eBay and I was promised provenance for them before I purchased.
The provenance was just made up, unverifiable rubbish and on closer inspection, the idols had flat backs as if they had been made from marble tiles (the backs should have been of a similar finish to the fronts).
Mike Davis did accept my returns and refunded all of my money (as eBay would have made him do anyway), although I am still out of pocket (return shipping) and very stressed out at being so stupid.
As soon as the idols were returned, he relisted them on eBay as genuine.
I am happy to send you copies of emails and any communication that I had with him.
