Wow - this posters is amazing!
Disney is pretty rabid about protecting their characters. They even sue daycares with unlicensed murals. I think they let the Wood orgy poster go because the guy who published it already beat them in a lawsuit over the Air Pirates comic - he was able to prove it was a valid satire. Rather than haul him into court again, Disney just went after people who bootlegged the Wood poster – I believe they won those cases. That was all around the late 60s though. From what I understand – someone please correct me if I’m wrong – since the 80s Disney has handled these cases differently. Even if they lost a case now they might just keep appealing the decision until the defendant ran out of money for legal fees.
