Design Cuts sells fonts, vectors, patterns, and other stuff, and also does freebies. The frame on this photo is from their current vector film textures freebie. I overlaid one of the frames on an image of a Herdwick ram and then reversed out the frame to get some contrast because the background to image of the ram is black.
If you are looking for other freebies, there is also Creative Market, which sends them out every Monday. Just sign up and you will get their email with the weekly offer.
