A piece of baggage comprising:

• a shell at least substantially enclosing an internal volume, the internal volume being configured and adapted to house articles for transportation;
• a receptacle operatively connected to the shell in a manner such that the receptacle is generally fixed in orientation relative to the shell;
• an identification card holder shaped and dimensioned to hold an identification card in a fixed orientation relative to the holder, the holder being attached to the receptacle in a manner such that the holder cannot easily be detached from the receptacle and such that the holder is selectively and alternatively movable between a retracted position and an extended position relative to the receptacle, the receptacle being configured and adapted to house the holder in a manner such that the holder is substantially concealed from an environment external to the shell when the holder is in the retracted position and such that an identification card being held by the holder will be substantially visible from the environment external to the shell when such card is held by the holder and the holder is in the extended position;
• and
• a towing handle and a towing handle cup, the towing handle cup being connected to the shell of the piece of baggage and having a recess formed therein that is configured and adapted to allow the towing handle to be stowed therein in a manner such that the towing handle lies substantially flush with the shell, the receptacle being rigidly fixed to the towing handle cup in a manner such that the holder extends at least partially into the recess of the towing handle cup when the holder is in the extended position relative to the receptacle.
