It’s weird that this looks like an edited picture to bypass dupe detection yet it’s from the actual Far Side website.

The bottom-left boards of the ship and water touching it have clearly had changes made. Also the three portholes in the middle. And in the sky at the top there’s some writing that’s mostly been brushed out.

I didn’t spend a tremendous amount of time looking, but I found a copy posted to Pinterest that looks like the original and more closely matches Larson’s usual style:

I could imagine wanting to remove the water spray droplets in case they wouldn’t be clearly printed in a black & white newspaper, but I don’t know if the new stuff was ever intended for that and it’s also odd that the cheetah in the porthole was also removed.
