An original photographic postcard of the Titanic, discovered in a Bristol, UK charity shop, is selling on eBay.
The rare shot was captured by Southampton-based photograph agency Willstead.
It shows the ship docked in Southampton and dates to 1912.
Postcards issued before the Titanic left port are referred to as pre-sinking, as they make no reference to the disaster.
Postcards sold after the tragedy would often be amended with a memorial message.
Volunteer Colin Richardson, who identified the card, told the Bristol Post: "The odds of finding it are just astonishing. That aspect of it did do my head in.
"I didn't realise how valuable it would be until I had gone online and saw one had sold for ?�250 in slightly better condition than ours�Ǫ
"It must have fallen out of a book but I have no idea which one.
"I have seen Titanic cards and probably come across them in other people's stocks, but in 12 to 15 years I never had one come into my possession. Especially this like the one we have got."
Bidding on the card already stands at ?�99 ($130) ahead of the July 24 close date.
Funds raised from the sale will go to Amnesty International.
