Thanks Michaël
On the basis of this image - slightly sharpened in photoshop, I now have little doubt that Ramona Fradon - respected DC artist, had a clandestine former career in her maiden name as Ramona Patenaude, and that for some reason she didnt want this known -or maybe no-one asked her the right questions! But my! she was young when she did this - a genuine prodigy I'd suggest. Unless she lied about her age, and what honest woman would do that - ummm!
Compared to this page found on the web, it's pretty evident that the same hand is at work - a rhythmic, slightly mannered style. I'd guess she "rehearsed" the motions then drew quite quickly.
Her lines have a way of wrapping themselves around the forms she describes - it's the sum total of all the lines that drops into place to create the likeness of reality in motion. Her creations arent "timeless", they exist in real time and engage with us - they have defined personalities.
The main change from early days with Fox is that she has learned to vary the thickness of her line - and knows that a line can be thickened on one side but thinned on the other so that it is asymmetrical, which creates the illusion of turning through space.
