A souvenir (from French, for memory) is an object that is treasured for the memories associated with it. This is analogous to the psychological exploitation of classical conditioning. For example, if a traveller buys a souvenir on a memorable vacation, the item chosen is likely to have an association with the holiday.
Souvenir is an album by Eric Johnson released in 2002. It is a collection of previously unreleased material spanning 25 years. The album was unique in that it was only available for purchase through Eric Johnson's website.
