It's a scale model of the Mos Eisley Cantina. It is made of wood, which had some advantages, but also some disadvantages when it came to manipulation. A lot of the other dioramas that I have seen of the Cantina are made in sections that fit together. This behemoth is one solid piece with a removable roof.
Since these photos were taken, I have picked up the new Hrchek Kal Fas (and a second to do the other alien that looks like this).... to replace my customs which were not very good. I also got the Leesub waitress chick. I have a pile of parts that I plan to use to do some more customs to finish the patrons, like the Tonnika sisters, the astronaut Danz Borin, and a few more.
This item is on the other half of the man-cave basement from my vintage GI Joe collection seen here:
