Lost vintage acoustic guitar with deep mahogany finish and distinctive travel stickers, last seen at a beach picnic area near Key Largo.

I lost my mom's vintage acoustic guitar while vacationing in the Florida Keys. It has a deep mahogany finish and a few distinct stickers on the back from different places we've visited over the years. I think I left it at a beach picnic area near Key Largo last Tuesday. It means a lot to me, so I'm really hoping someone can help me find it.
