Featured Walt Whitman engraving & others

Hi mate, i think i see where you mean, here right



interesting that that little area doesn't continue any where else

will have a look and try and get a shot (bit dark know )

 

i think you could be right !, definitely looks like something, doesn't occur anywhere else

 

Ah! Now we've spotted it, let's have a 'translation' of the Mystery Marks!

 

had a little clean of the area to try and make it clearer

 

found one the same, but doesn't have the marks and has a more tidy/later base

I don't see initials. Could be a symbol though. It looks deliberate, the other larger "butterfly" motifs have a trefoil springing from the centre instead.
