That’s Darth Vader’s Star Destroyer Playset under the Land of the Jawas Playset. Among the figures you can see the Hoth Stormtrooper, my third favorite ESB figure after the AT-AT Driver and Hoth Han. Hoth Luke is also there.
Two items I’d forgotten about are Star Snoopy Colorforms (1979) and Tomy’s Mr. Mouth (1976).
There were a couple of different versions of Mr. Mouth, one featuring a green frog as the centerpiece, the other featuring a dopey yellow guy. The dopey yellow guy is the one I remember, but I could only find a commercial for the frog version. The yellow figure was later repurposed as a Pac-Man bank, seen below via the 1982 Tomy catalog. I got Pocket Pac-Man as a stocking stuffer in ’81 or ’82, but I never did get Mr. Mouth.
I also had the Fisher-Price Play Family Fun Jet, seen at the far left of the original photo.
