I agree with the idea of Bacall at 17 - a figure of her in Poser would be a dream come true.

What about some of the following?

Lotte Lehmann
Marlene Dietrich
and the utterly luminous Louise Brooks (above)

And on the other side of the coin, what about Alain Delon when he was in his twenties? With respect to those who made these models, but he makes Don, James, etc. look rather flat...

(In case anyone wonders, no, I'm not that old, but the older stars had a glamour that I've never found in any of the modern stars...)
