Printed indie show tickets near Old Town Fort Collins

Yesterday around 3pm, I realized my two printed concert tickets for an indie show were missing somewhere in Fort Collins. They’re standard white tickets with blue print, about the size of a business card, with the stub torn along the left edge. The event is listed as 'Northbound Sessions' at the Lincoln Center near College Ave, in Old Town. I kept them in a small black canvas sleeve inside my backpack, and one has a coffee stain on the bottom-right corner; I really need them back—the tickets were a gift from my sister. If you found them near Walnut Street or Old Town Square, please message me; I’ll meet up to verify.
