**Please note the following:

1) This items picture will change once we update the listing to a new replacement specimen after this specific item has been sold, this action will cause the picture in your purchase history to also change to the new image.

2) The picture will also change if you've had the item in your basket for a while and someone else buys it during that period (having items stored in your basket does not remove that listing from the view of other customers, meaning it will still be active).

3) We would suggest saving, or taking a screenshot of the items image as soon as you have purchased it for your own records of comparison for once the item has been received in the post. We also keep a record of every image we upload.
