Here's a look at the original pencil layer of the painting, both before and after upscaling: For upscaling I used the ESRGAN model I've trained on posters by Drew Struzan, so the pencil work is interpreted based on his style. But I'd say it appears very faithful to what can be seen in the low resolution scan of Tiller's Ahern's original drawing, even if the detail is just created artificially. If the original background paintings were built the same way as the cover, they could probably be upscaled the same way as this (plus they'd still be at full color depth without dithering). If only those Photoshop files still existed somewhere...
