Gray queen duvet cover with white piping

I lost my gray Brooklinen duvet cover set yesterday around 3pm near the Mount Airy Casino Resort lobby in Mount Pocono. It’s a queen-size cover, soft percale, in a midtone gray with crisp white piping along the edges. Inside there’s a tiny monogram 'KP' on the inner tag, and there’s a faint coffee stain on the bottom corner from a spill last week. It was a gift from my sister and holds sentimental value, so I really need it back. If anyone finds it, please DM me here or email me at [email protected]—I'll be incredibly grateful.
