Vintage 1980s Darth Vader action figure

I lost my vintage Darth Vader action figure yesterday afternoon around 4pm outside the Starbucks on Wick Avenue by the YSU campus. It's a 1980s Kenner figure, all black plastic with a slightly glossy finish and a removable red lightsaber. It has a small tear along the edge of the cape and a tiny red sticker with the initials 'JP' on the back of the helmet. I last had it in my backpack after lunch, and then I headed toward Market Street, but it was gone when I reached my car. It means a lot to me—it was a gift from my dad—and I’d be really grateful to get it back!
