This is a 1960s vintage carry-on hard shell case made in an attractive octagonal shape - I think that this was designed to carry a wide brim hat, but one could carry a number of personal items in it.  It was made in Canada by Dominion Luggage as part of their “Jetliner” line - note the jet that is part of the logo.  it opens with two tabs, but I don’t have the key that would lock them.  The interior of the piece is lined in quilted red satin that is covered with clear vinyl.  The exterior is made with a pebble finished hard shell vinyl in a dark grey colour.  The piece measures 16” by 19” including the unextended handle and the feet at the bottom.  It has a thickness of 5 1/2”.  It is very clean on the interior - there is a slight scent, but I will air it out and it should be fine.  The exterior only has a couple of scratches where a brown undertone is showing and some wear/discolouration to the metal framing in places (see last two close-up photos).  Otherwise, this displays wonderfully.  The price includes shipping, but please contact me for a price as I may be able to do better depending on your location.  This is a wonderful piece of vintage luggage - fun streamlined octagonal shape!
