The collector market for film fans has evolved quite a bit from when I was a young fan. Sure, there were opportunities for me to spend my money, but these days, there are so many better opportunities and better items. There's the entire poster phenomenon, best embodied by the success of Mondo, which has spurred what feels like an entire industry. I recently got talked into joining some commission groups, so now I've got some ultra-limited art coming my way that I look at as even more special because I had a hand in designing it.
It was inevitable that soundtracks would also end up being major collector pieces, and one of the great frustrations for me when I was a younger film fan was realizing just how random the process is by which scores get released. There are some great companies now doing important archival work, like La-La-Land Records, and recently two titans in the collecting world merged, resulting in Mondo's Death Waltz Recording Company, which is poised to own your wallet for the near future.
