So here we have Cyllene Moxon, sometimes known as Seline, and at others Selene. Yet she is here is not purely because of her beauty, or her romantic life story, but because these cards are usually referred to as "Actresses - Chocolate"
She appears on several other cards in the collection of the New York Public Library I am pretty sure that Cyllene was not her given name, as Cyllene is a nymph in Greek mythology, actually the daughter of Zeus.
Our Cyllene is rather unkindly often called “a society girl”, but she was very beautiful and she caught the eye of lots of men, including several of the early aviators, supposedly Gustav Hamel in particular, but I cannot track this down, yet.
Then she met Ernest Frederick Wilton Schiff, who boasted of having been expelled “from Eton”, though it may well have been another school, and was well known for being involved with beautiful ladies, one of whom was Liane de Pougy. Cyllene became his long-term mistress, and they lived together in Brighton, enjoying what is was called in the papers “a somewhat scandalous lifestyle”, which makes it sound like the writer didn’t really know what they did, or he could have reported about it a lot better.
When Mr. Schiff died, he left her an annuity for life, but she freely admitted their relationship was never about the money. However, after he died, and perhaps before, she was involved with his nephew, who was killed in Cornwall in a row over another girl.
The Schiff family website will tell you much more about all this.
After that she became very good friends with the actress Sunday Wilshin from 1932 until 1960, and Noel Streatfield the author.
She died in August 1970.
