Concert tickets in white envelope with blue sticker

I lost two concert tickets yesterday around 3pm near Plemmons Student Union on Rivers Street in Boone. They're printed on regular white stock and came in a slightly crumpled envelope with a blue sticker labeled B12. I had written my name in blue ink on the back and folded it once to fit in my pocket. The show is this weekend, and the tickets are all we had planned for a little weekend outing with my sister. It would mean a lot to get them back; they're not just tickets, they're a small reminder of a promise we made. If you found them, please reach out.
