Two blue concert tickets with holographic sticker

I found two blue concert tickets this afternoon around 4:15pm, tucked under the bench by the Cotton Exchange on North Front Street in Wilmington. They're for a show at a small downtown venue next Friday; the tickets have a bright blue background with a holographic star and a perforated edge. One ticket has a tiny coffee ring stain near the bottom, and the barcode area looks slightly creased from being in a pocket. They’re for 'Aurora'—the date printed is clearly visible despite the crease. If the owner is out there, I’m hoping they’ll recognize the color, the holo star, and the coffee ring and can claim them near the Riverwalk.
