The Holy Grail of Marx Playsets?

A very very enthusiastic seller on Ebay has for auction something that would get all serious Marx collectors foaming at the mouth: an unopened Flintstones Hunting Party playset. I've tried doing research on why this set is so sought-after, but all I know is that not that many were made and it is the most detailed set of anything Marx did. I'm trying to find pictures of the items themselves, but even those seem to be rare.

























Here are some excerpts from the Ebay listing. "Richard Koch, a well known collector, said that this set was a "seldom seen, large scale playset that topped the Marx list". "It came in a great litho box with artwork that makes the set extremely desirable not only for playset enthusiasts, but to Hanna-Barbera character collectors as well. The figures of Fred and Barney (the only character figures that come in the set), are grey soft plastic and stand 3"tall; the three prehistoric animals are in a matching scale and are in cream and light brown. Palm trees also came with this particular set." FROM THE COLLECTION OF A SOLDIER/PLAYSET COLLECTOR WHO PASSED AWAY!!." Guess he never got the chance to open it.

Looking forward to seeing how high it sells for......
