I dragged this image (a capture I initially took quite awhile back off part of the cover of an issue of The Economist) onto the camera roll of my XR and then took a screenshot of it so it ended up on a black background, then shrank that image slightly to end up as the XR's lockscreen.
I love using image captures off the net as desktop photos or mobile wallpapers for awhile as a change from photos I've taken personally. Over the years I've leaned to make a point of filing notes at the same time on all due credits for the images I capture. I'm embarrassed that I've no clue even as to which issue of The Economist had featured the art on my phone's lockscreen at the moment, never mind a photo credit.
