Movie question

[Kongde]

I was browsing movies and series to buy and wanted to buy one of the ROTK movies, 1994 or 2010 version, no preference, since I have already seen both and just wanted to add the movies to my physical collection.

Anyhow, I came across this odd boxset which included a 2006 sampler.






I have attempted to search for this exact boxset but have come to no avail. I do know this is the 1994 version, but the seller has it listed as a 2007 DVD edition. Unfortunately no results pop up upon searching ROTK 2007 DVD, at least pertinent to this boxset with a 2006 sampler. The other boxsets do not look like this, and I know of at least 2 other boxsets that look different.

Can anyone provide any insight on this?
