Åland is home to one of Europe's largest collections of photography equipment and the souvenir sheet on this cover commemorates the 25th anniversary of the museum that holds that collection. I'm pretty sure the character in the middle of the stamp is Olle Strömberg who founded the museum in 2001 with his wife Benita. She's on the sheet too. In the framed photo on the left. The "Camping" postmark is a seasonal thing, available from Åland Post between May and August. Camping is very popular in Åland as it is in all Scandinavian countries.
