Look closely at the photograph. What do you see on the shelves? Books? Wrong! These are fish conserves.
This small shop in LX Factory in Lisbon sells traditional Portuguese sardines in cans. Each can has a different year to allow buyers to purchase fish from the year they were born. Just kidding! The fish are fresh and are souvenirs that can be bought from Lisbon to keep and to give as a gift to someone.
