I think this is the last year the major catalogs sold Marx playsets, thanks to Kenner’s revolutionary Star Wars toy line. The Iwo Jima Jungle Mountain looks exactly the same as Navarone, except that Navarone is a grey-blue.
The Hulk Play Case looks even lamer and junkier than the Buck Rogers one I had. These cases were made of vinyl, and the attachments were cardboard.
I like how they used Godzilla’s foot to demonstrate elastic Superman.

Geez, you gotta quit with those epic WWII mountain fortress play sets! You’re gonna force me to search on Ebay for those darn things…ugh!
A nearly complete Navarone set, with a very beat up box, just went for $82 on eBay. Plus $20 for shipping.
lol, no thanks. I’d be much happier to find it at a yard sale for $50 or something (yeah right).
