I don't know who made that piece but usually when a room is featured in magazine spreads and on design blogs, sources and other info is listed somewhere. You just have to click through until you get to it. If you don't get results quick enough that way, you can always try asking the stylist, interior designer, blogger, or magazine. (Magazines used to publish this stuff routinely before the internet. I dunno how they do it now, I haven't looked at magazines in many years.)
