Any one know the artist and the name of the large picture on the wall in episode 5 at time 00:45:00.
I don't think it is a movie prop. I like it and want to see it in real...

Hey,
I haven't watched the drama but took a screenshot of the picture you're talking about & did reverse image search and found this: http://www.seoulmuseum.org/nr2/?c=exhibition&memoryuid=9 it's the third pic one that page of the museum's site.
The title is something with pine trees x)
Hope it helps!

Edit: the artist's name is Moon Bong-Sun and the English title of the pic is "Pine Tree — Gyeongju Samneung Pine Tree Forest" (source)
Whaaa. Thank you very much for info. One more reason to travel to Seul.

PS: reverse image search - totally forgot about this one. I remember someone using this algorithms at my UNI to take down a professor of his team leading position. He searched the pictures from his publications with it.
Glad I could help :)
Yeah reverse image search can be quite useful :P
