I check sites that list hardware specs, and once I find a phone that seems interesting for an average price I’m willing to pay, I check places like XDA to know how much of a hassle it’ll be to unlock the bootloader and add a custom ROM. And if modding the phone has too many/too big drawbacks, I return to the first step until I find a phone that seems good.
I think I found the name. According to the page https://www.chigozieobi.com/comingupforair, it is a two-pieces painting called “ADORNED (DIPTYCH)”.
