Thierry, I think the rise of collectibles (not only movie posters, but also comics and trading cards) these days is a direct result of the stock market tanking. I see the exact same phenomenon with fine art auctions, where prices have exploded since the beginning of the pandemic. A lot of people who used to invest their disposable income in stocks when the market was going strong have now turned to other forms of investment, from real estate to art and collectibles, because those currently offer better short-term returns. It's not like there are a lot of different options when it comes to parking one's money.
