19th-Century Yong-wang  Dragon-King  Painting
in the National Museum of Korea
(Yongsan District, Seoul)
original enshrinement and artist unknown
This is actually a Shinjung-taenghwa [Assembly of the Spirits Altar-Painting],
but it features the
Yong-wang [Dragon-King of the Waters] in its center.  It is
one of only a handful of such cases among antiques remaining in Korea -- I've never found
a modern one.  Sharing the center to the right is what may be a
San-shin, but I'm not sure.  
The
Dongjin-bosal who is usually at the center of these icons is to the upper-right instead.  
The eight other figures are mostly of fish-spirit types, continuing the Yong-wang-centric motif.
