Easter egg or...?

what is that? ?

Lol same after a zoom of 70% I cannot read. I see something like Cool. Not sure

I found 2 things:

  1. t.opf = topf (german) = pot/pan
  2. topf from Topf & Soehne: a company that was entangled with the politics of mass extermination in national-socialist Germany. It produced crematories as well as parts of the gas chambers.

???

I think it is the signature of the guy who drew the island.

 

I’m going with your answer. I think the other islands also have initials, though I don’t think they’re all the same.
