Natural Yamaha FG800 acoustic guitar with sticker

I lost my Yamaha FG800 acoustic guitar yesterday around 3pm. It's natural wood with a satin finish, about 40 inches long, and there's a small dent on the lower bout. A faded sticker sits on the pickguard, and a bright green strap with a white sunburst pattern is attached. I left it near The Strand outside the Grand 1894 Opera House on Postoffice Street in Galveston. This guitar has sentimental value—it's the first grown-up instrument I saved up for, and I really need it back.
