I'm new to the forum. But what better thing to post about first, than to say - wow. That's a truly incredible collection.
I collect also, though only a tiny collection of discs and memorabilia compared to that. And I've recently got back into buying physical media, after tiring of streaming and ripping etc. But I understand the collecting bug well, because I have also been a toy collector for over 25 years, and have a small showroom setup for those (its much bigger than my film collection).
Anyway, thanks for sharing your video. That collection is phenomenal. And I know the effort and cost it would have taken.
