User blog:Belle pullman/Photo Cropping Question?

Ok, so generally speaking, I'll edit photos and crop off white spaces around the actual image - the borders distract the eye from the content.

But what about when it comes to Polaroids, like this one? Would it be better to crop it down, or leave the distinctive white frame? In this particular example it's a fairly recent (2014) image, but the analogue format makes it seem much older. This is only really explained by the fact it is specifically a Polaroid, when you'd expect a digital camera image. But, regardless of brand of camera, the white border is a distraction... what's more important, explaining the quality or focusing on the image?
