Framed abstract painting with blue-gold swirls

I found a framed abstract painting this morning around 10:15am on Lincoln Road near the Washington Ave intersection in Miami Beach. It's a 22x28 inch piece in a matte black wooden frame, with bold swirls of cobalt blue, teal, and metallic gold on a white field. There’s a small scratch along the bottom edge and a faint artist signature on the back that reads 'L. Rivera 2022'. It looks like a professional gallery piece, and I figured someone might be missing it after a stroll along the beachside sidewalk. If this sounds like yours, we can arrange a pickup near Lincoln Road.
