@UlricKerensky once asked me for better quality images used in creating the logo. Due to sync rot, I no longer have the full set. I have the tree: I'm missing the pretty face. IIRC I found it doing a Google Image Search for "eugenics". The faces on either side should be easier to find. They're Neanderthal reconstructions. I might have them. The tree+face is the tricky bit.
