Found vintage Star Wars action figure set

Found a vintage Star Wars action figure set this afternoon around 2:15pm along the Riverfront Park walking path by the Main Street bridge in Pierre, SD. The set includes two 3.75-inch figures in their original blister packaging, with blue cardbacks and a slightly yellowed price sticker from the 1983 catalog. The box shows light edge wear and a small crease along the top flap, but the figures themselves look untouched. A tiny red 'QC' dot on the back and the 'Kenner 1983' text on the side are nice identifying details. It seems like something a collector would miss badly, and I’d love to get it back to its owner. Reply with the catalog year stamped on the back or the red dot location if this sounds like yours.
