Concert tickets found near Soaring Eagle, Mount Pleasant

I found a pair of printed concert tickets this afternoon around 2:15pm, lying on the ground near the entrance of the Soaring Eagle Casino & Resort on S Mission Street in Mount Pleasant, Central Michigan. They're glossy, standard-size tickets with a purple-to-blue gradient and a barcode, and the seating is listed as Section B, Row 4, Seats 8 and 9 for an upcoming Friday show. They were tucked into a small crumpled envelope with a handwritten 'Return to owner' note and a tiny blue sticker bearing the initial H. If this belongs to you, please reach out so I can help you get them back before the event.
