Sometimes people forget to remove things from items before donating to charity. And such was the case when a rare Titanic postcard slipped out of a book donated to Books For Amnesty in Bristol, UK. The card, which shows Titanic docked in Southampton before its maiden voyage, is dated to 1912. And was done by a local photographer.

Colin Richardson, a volunteer at the store and has an interest in postcards himself, was astonished at the remarkable find. The card has been put up for sale on Ebay and could fetch close to £99 ($130).
