Got the April 1995 issue of Classic Images which had an article about
Olive in it. Apart from mis-stating that she and Jack were staying at
the Crillon hotel (instead of at the Ritz) it was a reasonably good
article with a couple pictures (if you have Kenneth Anger's book you
have the same pictures).

Also picked up a 1976 reprint of the 1920 "Who's Who on the Screen". A
nice goldmine of silent screen actors and directors. Also has pix of
the early film studios including not-yet-finished Long Island City
film studio Paramount was building.

Assuming the reprint was 100% faithful to the original, the book is
rather poorly laid out - no table of contents and bio pages aren't in
any sort of order. Good thing there's an index.

Olive and Jack are on pages 132 and 133 so at least they're together.
Jack's sister Mary is way over on page 87.
