The Altadena Historical Society (of which we are members) has a great story in their Sept. newsletter on fires in 1934 and 1935, which endangered La Vina and the Cobb Estate (click to get the pdf version).
Jane Brackman of the Historical Society says:
Every once in a while Altadena Historical Society sends out information on cool stuff from their files. No membership is required. If you would like to receive the email attachments let Jane Brackman know. Her email is firstname.lastname@example.org
BTW– the photograph of the Cobb home featured in the attachment is one of a very few that exist. If any readers have a picture of the house tucked away in their family papers, please please please let us know.
