I don’t know the name of Mother 15, on my Patchwork Of Mothers, except that she is Pam’s mum from the 1988 Little Star annual. Nor, sadly, can I find the name of the illustrator.
All I know about Pam’s mum is, she likes birds, like Snow White.
The legs above Pam’s mummy belong to Barbra Streisand.
I can only find this page from the book (see below), although the rest is probably somewhere in the house.
