Lost black Fender Stratocaster electric guitar with distinctive stickers in a padded gig bag at a music festival in East Anglia.

I lost my black electric guitar, a Fender Stratocaster, while visiting a local music festival in East Anglia last weekend. I remember placing it on the grass while I was taking a break, but when I returned, it was gone. It has a few distinctive stickers on the back and was in a padded gig bag. Any help in locating it would be greatly appreciated!
