John,
 
Jim Bramlett's letter about the National Geographic 'find' is astounding and, as usual it all 'adds up'.
 
First they say the bones are 3.3 million years old.
Then they say the 'child', a girl,  was about 3 years old when she perished.
 
So, in this article, National Gegraphic have been bold enough to present its readers with not just a '33' signature but a '333' signature as well.
 
Discerning Doves will have noticed another fairly recent occurrence of the '33' signature where the Israel war in Lebanon lasted exactly 33 days and with another website also reporting that the Israeli military suffered 33 deaths.
 
Blessings to you all,
 
Phil.

Thanks, Phil.
