Lost bright blue and yellow soprano ukulele with floral pattern sticker at a park bench in Essex.

I lost my bright blue and yellow ukulele while I was sitting on a bench at the park in Essex around 3 PM yesterday. I remember placing it beside me while I was talking to a friend, and we then got up to leave without it. It's a small soprano ukulele with a floral pattern sticker on the back. I'm really hoping someone picked it up and can return it to me!
