If this is a purchase you have made, find the transaction in your Purchase History using a desktop browser and click on the item title. When the page loads, see if there is a note in a band at the top indicating if the listing has been revised or removed; there may be a link to the original listing there. If the title appears but is not an active link, try the thumbnail image.
If there is no notation in the band at the top other than an indication that the item has sold, scroll down past the sponsored listing links to see the listing.
