Big Golden Record DBR-2 Six Songs from Alice in Wonderland - Part 2
Second in the series, and probably rarer still than Part 1, but who can say for sure? I've only ever seen two copies of each with their sleeves and maybe an additional 4 of part 1 without. Regardless, insanely rare doesn't even begin to cover it. I know the WDL-4015 is rare and valuable, but it is way more common than these.
Same additional titles on the back of both parts 1 and 2. I've seen Peter Pan DBRs too, and a Jiminy Cricket MMC title that escapes me at the moment, but Disney titles in this format are small in number.
