A Memorable Connection
I found the document below an interesting point in time. Michael Morris receives written permission from Natacha Rambova's former love and financé, Svetoslav Roerich, to reproduce the painting of her on the back cover of Madam Valentino. It is, in a way, a direct connection between Michael Morris and his great subject and although Svetoslav was a very elderly gentleman at the time, he lived long enough to grant the permission.
There are some interesting videos of the elderly "Svetie" on Youtube; a fascinating and an iconic life.
