Sorry guys. I was using the list of published materials in the back of the Schroder book, and I guess she chose not to list the Oak book. I should have done a search first.
There used to be broadsides of some of her songs around Berkeley, too, and though I don't have them anymore -- too many moves -- Schroder may know something about them.
If I can get a friend to scan a poster for me, I'll post a picture of one, and you can have one for a $15 donation to Mudcat. PM me if you're interested.
Blessings,
Barbara
