Framed teal-and-gold abstract painting

I found this framed teal-and-gold abstract painting this afternoon around 3:15pm outside Northpark Mall on Main Street in Joplin. It's a 16x20 inch canvas in a matte black frame with a few minor nicks on the edge. The swirls are teal and cobalt blue with hints of copper that catch the light, and there's a small white signature 'L. Rivera' in the bottom right corner. On the back, there's a dusty gallery label and a tiny coffee ring mark on the frame. If someone is missing this piece, send me a note here and we can arrange a quick pickup at the Northpark entrance.
