Lost valuable vinyl record of 'The Dark Side of the Moon' by Pink Floyd in a black sleeve in Holland.

I lost a valuable vinyl record of 'The Dark Side of the Moon' by Pink Floyd while I was visiting a friend's house in Holland. I took it out to play it and must have left it behind after we finished listening to it. It’s in a black sleeve and has a couple of slight scratches, but overall, it’s in great condition considering its age. It has significant sentimental value to me, so I’d really love to get it back.
