I have never seen this empty box for sale. You can use it for display or fill it with the special Cantina playset which is totally different from the Kenner one. Look on the box and you will see, for example....
The paper and silvery entry doors are different, shape of the floor, the footprint of the playset, the bar is cardboard and folds and inserts into playset with plastic bar top. Side round table pops in instead of being attached. There are foot peg levers for the figures... Totally different than the Kenner one!
