Hello again,

I just posted some food for thought on the web in the form of a comparison
photograph of two S-A specimens. One is the 'primitive' individual that has
gone through less human cosmetology, while the other is a more recently
acquired piece that most likely has had its share of visits to the beauty
parlor.

The differences are subtle, but they are there.

Any other thoughts or observations?
