/lit/ - Literature

I haven’t been on /lit/ for years, and I see this thread. It is good because I started collecting old books.
I usually buy them from antique markets for less than 10 euros.
I am also an antique dealer and I usually sell paintings.
Is the market even worth it nowadays? Should I take some time set up a small book business on the side? I don’t have a huge stock, I collect them for fun and also because I can find them cheap.

Pic related, bought it this morning. A pleasant surprise. I also bought a first edition of Elisabeth Bowen’s To the North, signed copy, 1933. Both for 8 euros.
