Framed teal-gold abstract painting found downtown Sioux Falls

I found a framed teal-gold abstract painting this afternoon around 2:15pm behind the SculptureWalk display on 8th Street near Main Avenue in downtown Sioux Falls. It's about 18 x 24 inches, with bold teal and metallic gold swirls on a deep navy background, housed in a black wood frame with a small scratch on the lower-right corner. On the back there's a white label reading 'L. Kim 2017' and a faint handwritten note. The piece looks slightly warped, but otherwise in good condition. If this belongs to you, I'd really like to help reunite you with it—I can't imagine losing something that looks this unique.
