For those who have asked, these are the last of the 52 WEEKS::Heroes series:
Top Row: Mary Cassatt, Buffy Sainte-Marie, Louisa May Alcott, Stevie Nicks, Anais Nin, Mata Hari
Bottom Row: Doris McCarthy, Sandra Dee, E. Pauline Johnson, Kenojuak Ashevak, Emmeline Pankhurst, Karen Blixen
They are still available for the introductory fee of $150 each and there are also a few books still available for $25 each (see link here for a preview).
Again, huge gratitude for all the support on this series...it really was a work of the heart.
