This is a 1970s-1980s American Tourister brand brown nylon & leather Oversize Weekender Carry-On Luggage bag.
Bag has 6 "feet", three large compartments, and a removable shoulder strap (with rubber grips).
While I'm certain this was considered a "carry-on" bag at the time of its creation, by today's standards, it toes the line as it's quite large.
Bag measures approximately 19" L x 14.5" H x 4.75" W.
Bag is composed of brown nylon with brown leather trim. The American Tourister logo is small and placed on the right side (near where the shoulder strap attaches).
The first interior compartment has no pockets. The middle section has a stiff bottom support so the bag keeps its shape, and one large slip pocket that runs its entire length. The third compartment is like the first - open space with no pockets.
Handle straps have a button closure to keep them together.
Silver-tone hardware.
Condition-wise, the bag has a few minor aesthetic flaws, including a large discolored striped across the bottom. The feet show use, as they have some slight scuffing. There are 2-3 spots with tiny white spots on the nylon, and the back of the bag has some scuffing/white discoloration on the leather trim. Structurally, however, the bag is fine and it's oversized so that you can bring only this bag and nothing else.
