While it may seem really clear to you that the photo you are offering is a rare item, you must keep in mind that your auctioneer may not know this. Take note of what is different about whatever it may be, and place the info with the piece. The auction hall could very well determine that the info is important enough to put on the company website.Successful selling at auction is never about mindlessly throwing stuff into the car and leaving it with the auctioneer.
